Before storing your RV for the winter, a thorough cleaning and inspection are essential to ensure it’s in great shape when you’re ready to hit the road again.

Dirt, grime, and moisture can accumulate over time, potentially causing damage or making it harder to deal with come spring.

Here’s how to properly clean and inspect your RV for winter storage:

Exterior Cleaning

Start with the exterior of your RV to prevent long-term damage from the elements.

  • Wash the RV: Use an RV-specific cleaner to wash the entire exterior, including the roof. Pay special attention to areas like the awning, windows, and slide-outs. Remove any dirt, bugs, and road grime that have built up during your travels.
  • Wax the Exterior: After washing, apply a high-quality wax or sealant to protect the RV’s surface from snow, rain, and UV rays. This will help prevent fading and cracking over the winter.
  • Clean the Roof: If your RV has a rubber or fiberglass roof, be sure to clean it thoroughly. Check for any signs of wear, cracks, or potential leaks. If you notice any damage, repair it before storage to avoid costly water damage.

Interior Cleaning

The inside of your RV is just as important to prepare for winter.

  • Deep Clean the Interior: Vacuum carpets, sweep floors, and wipe down all surfaces. Be sure to clean hard-to-reach areas like under furniture and appliances. This will not only keep the RV fresh but also help deter pests from making your RV their winter home.
  • Clean Out Cabinets and the Fridge: Empty all food from the cabinets, refrigerator, and freezer. Any remaining food can attract pests, which may cause extensive damage over the winter. Clean and wipe down these areas with a disinfectant or a natural cleaner.
  • Leave the Refrigerator and Freezer Doors Open: Once cleaned, leave the doors slightly ajar to prevent mold or mildew from forming inside. You can also place moisture absorbers or baking soda inside to help eliminate any odors.

Inspect for Damage

A careful inspection now can prevent major issues when you take your RV out of storage in the spring.

  • Check Seals and Weatherstripping: Inspect all seals around the windows, doors, and slide-outs for cracks or gaps. Replace any damaged seals to ensure your RV is watertight during the winter months.
  • Inspect the Roof and Windows: Look for any signs of leaks, such as discoloration or soft spots on the ceiling or around the windows. Even small leaks can cause significant damage if left unattended throughout the winter.
  • Check for Rust and Corrosion: Inspect any metal components, such as the chassis and tow hitch, for signs of rust or corrosion. If you find any rust spots, clean them and apply a rust inhibitor to prevent further deterioration.

Final Touches

  • Remove and Store Personal Items: It’s a good idea to remove valuable items and personal belongings from the RV before winter storage, especially if your RV will be stored in an uncovered or unsecured location.
  • Shut Curtains or Cover Windows: Closing your curtains or using window covers will prevent sun damage to your RV’s interior over the winter. It also helps keep prying eyes away from the contents inside your RV.

A thorough cleaning and inspection will not only protect your RV from the elements and pests during winter storage but will also make it much easier to get back on the road when the warm weather returns.

Step 2: Drain the Water System

One of the most critical steps in preparing your RV for winter storage is properly draining and winterizing the water system.

Any remaining water in the pipes, tanks, or water heater can freeze and cause severe damage. Here’s how to safely drain the water system and prevent costly repairs:

Drain the Fresh Water, Grey, and Black Tanks

Before you begin the winterization process, it’s essential to empty all the water tanks in your RV:

  • Fresh Water Tank: Start by completely draining the fresh water tank. You can do this by opening the drain valve located under the RV. Once drained, keep the valve open to ensure no residual water remains.
  • Grey and Black Water Tanks: Next, empty the grey and black water tanks at an appropriate dump station. After draining, it’s a good idea to flush the tanks to remove any lingering waste or buildup. You can use a tank cleaning wand or an RV-specific tank treatment to ensure the tanks are as clean as possible before storage.

Drain the Water Heater

After emptying the tanks, the next step is to drain the water heater:

  • Turn Off the Water Heater: Ensure the water heater is turned off and has had time to cool down before you begin.
  • Release Pressure: Open the pressure relief valve on the water heater to release any built-up pressure inside.
  • Drain the Water Heater: Remove the drain plug (often called an anode rod) to drain the water heater completely. The drain plug is usually located on the exterior of the RV, near the bottom of the water heater compartment. Be sure to check the condition of the anode rod. If it’s corroded or heavily worn, now is a good time to replace it.

Bypass the Water Heater (If Equipped)

Many RVs are equipped with a water heater bypass valve, which allows you to winterize the plumbing system without filling the water heater with antifreeze. If your RV has this feature, activate the bypass valve after draining the water heater. This will save you a significant amount of antifreeze and make the process easier.

Use RV Antifreeze

To prevent freezing in your RV’s water system, it’s important to run non-toxic RV antifreeze through the plumbing:

  • RV-Specific Antifreeze: Make sure to use antifreeze that is specifically designed for RVs and safe for drinking water systems. This antifreeze is non-toxic and won’t damage your plumbing.
  • Water Pump Method: Begin by turning off your water pump and opening all faucets to relieve any pressure in the lines. Next, close all faucets. If your RV is equipped with a water pump converter kit, use it to draw antifreeze directly into the system. Turn on the water pump and open the faucets (starting with the one furthest away from the pump) until you see antifreeze flowing out. Don’t forget to run antifreeze through the shower, toilet, and any outside faucets as well.
  • No Converter Kit? No Problem: If your RV doesn’t have a converter kit, you can still pour antifreeze directly into the fresh water tank and use the water pump to circulate it through the system. However, this method requires more antifreeze and may not be as efficient.

Protect Appliances

Certain RV appliances also require winterization:

  • Drains and P-Traps: Pour a small amount of antifreeze down each drain (kitchen sink, bathroom sink, and shower) to protect the P-traps. P-traps are prone to freezing, and a burst trap can lead to costly repairs.
  • Toilet: Flush antifreeze into the toilet to protect the valve and internal parts. Be sure that antifreeze has entered the black tank as well.
  • Outside Showers or Faucets: Don’t forget any exterior water points. Open the taps until you see antifreeze flowing through to ensure those lines are protected.

Blow Out the Lines (Optional)

For added protection, some RV owners prefer to blow out the water lines with compressed air in addition to using antifreeze:

  • Compressed Air Method: After draining the water tanks and water heater, you can use an air compressor to blow out any remaining water from the lines. Attach the compressor to the city water inlet using an RV blowout plug, and run compressed air through the system to clear the lines. Keep all faucets open while you do this.
  • Follow Up with Antifreeze: Even after blowing out the lines, it’s still recommended to run antifreeze through the system to ensure full protection from freezing.

Final Checks

Once you’ve completed these steps, double-check your RV’s water system:

  • Open All Faucets: Open each faucet one last time to ensure antifreeze has been evenly distributed throughout the plumbing.
  • Inspect for Leaks: Look for any leaks or drips that could indicate an incomplete winterization. Address any issues before closing up the RV for the season.

Properly draining and winterizing your water system is a crucial part of winterizing your RV for storage. Following these steps will protect your pipes and tanks from freezing, ensuring your RV is ready to go when warmer weather returns.

Step 3: Prepare the Batteries

Properly caring for your RV’s batteries during winter storage is essential to ensure they stay in good condition and last as long as possible.

Failing to maintain your batteries over the winter can result in them losing charge or becoming damaged, leading to costly replacements. Here’s how to prepare your RV’s batteries for winter storage:

Disconnect the Batteries

When storing your RV, it’s important to disconnect the batteries to prevent them from draining while the RV is not in use:

  • Turn Off Power: Before handling any batteries, ensure that all electrical components in your RV are turned off to avoid any accidental power draw.
  • Locate the Battery Switch: If your RV is equipped with a battery disconnect switch, use it to disconnect power from the RV’s battery system. This isolates the batteries from any devices that might draw power while the RV is stored.
  • Physically Disconnect the Batteries: For RVs without a disconnect switch, manually disconnect the negative cable from each battery terminal to stop any power from being used. Make sure to remove the negative terminal first, followed by the positive terminal. This is a crucial safety step to prevent accidental sparks.

Clean the Battery Terminals

Battery maintenance isn’t complete without cleaning the terminals, which can corrode over time:

  • Inspect for Corrosion: After disconnecting the batteries, inspect the terminals for signs of corrosion—this often appears as a white, powdery residue.
  • Clean the Terminals: If you see any corrosion, clean the terminals with a mixture of baking soda and water. Use a small wire brush or an old toothbrush to scrub the terminals clean, then rinse them off with water. Make sure the terminals are completely dry before proceeding.
  • Apply Terminal Protectant: Once the terminals are clean and dry, apply a terminal protectant or dielectric grease to prevent future corrosion during storage.

Remove and Store the Batteries

If possible, removing the batteries from your RV and storing them in a climate-controlled environment is the best way to protect them during the winter:

  • Remove the Batteries: Carefully lift the batteries out of the RV. Batteries can be heavy, so take your time and use proper lifting techniques to avoid injury. If your RV has more than one battery (for example, house and chassis batteries), remove them all.
  • Store in a Cool, Dry Place: Store the batteries in a cool but not freezing environment, such as a garage or basement. Batteries stored in extreme cold or hot temperatures can lose charge faster and suffer damage. Aim for a location with temperatures around 50°F (10°C) if possible.
  • Use a Battery Tray or Mat: Place the batteries on a non-conductive surface, like a wooden pallet or rubber mat, to avoid discharging through contact with concrete or other conductive surfaces.

Use a Trickle Charger or Battery Maintainer

If you’re storing your RV batteries for an extended period, using a trickle charger or battery maintainer can help keep them charged without overcharging:

  • Trickle Charger: A trickle charger provides a low, steady charge to the batteries, keeping them topped up over the storage period.
  • This is a good option if you won’t be regularly checking on your RV’s batteries.
  • Battery Maintainer: A battery maintainer (also known as a smart charger) monitors the battery’s voltage and automatically supplies charge only when needed. This helps prevent overcharging and extends the life of your batteries.
  • Check on the Batteries: Even if you’re using a trickle charger or maintainer, it’s a good idea to check on your batteries periodically during the winter. Make sure they’re holding charge and inspect for any signs of corrosion or damage.

Check Battery Fluid Levels (For Lead-Acid Batteries)

For lead-acid batteries, it’s important to check the electrolyte levels before storage:

  • Inspect the Fluid Level: Open the battery caps and check the fluid level in each cell. The electrolyte should cover the plates inside the battery. If the fluid is low, add distilled water to bring it to the proper level. Avoid overfilling, as this can cause the battery to overflow during charging.
  • Avoid Tap Water: Always use distilled water to top off the battery cells. Tap water contains minerals that can reduce the performance and lifespan of the battery.

For RVs Stored with Power

If you’re storing your RV in a facility where it will remain plugged into shore power, some additional steps will help you care for the batteries:

  • Monitor Battery Charge: If your RV will be connected to shore power, make sure your converter or inverter has a multi-stage charger to avoid overcharging the batteries. This will help maintain the battery at a safe charge level.
  • Check Water Levels: Even when connected to power, the batteries can lose water through evaporation, so regularly check the electrolyte levels and top them off as needed.

Reinstalling the Batteries in the Spring

When spring rolls around and it’s time to reinstall the batteries:

  • Check the Charge: Before reinstalling the batteries, check the charge level using a voltmeter. Fully charged batteries should read around 12.6 to 12.8 volts. If the battery charge is low, recharge it before reconnecting it to the RV.
  • Reconnect the Batteries: Reinstall the batteries in the RV by reconnecting the positive terminal first, followed by the negative terminal. Be sure all connections are tight and secure.
  • Test the Electrical System: Once the batteries are reconnected, turn on the electrical system and test all major components (lights, appliances, etc.) to ensure everything is working properly.

Properly preparing and storing your RV batteries over the winter can save you from unexpected problems when you’re ready to get back on the road. By following these steps, you’ll extend the life of your batteries and ensure they perform well for seasons to come.

Step #4 – Protect the Exterior

Washing & Waxing RV

The exterior of your RV is exposed to the elements year-round, but winter presents unique challenges. Snow, ice, and cold temperatures can damage your RV’s exterior if it’s not properly protected.

Taking the right precautions now will save you from expensive repairs and help preserve your RV’s appearance and functionality. Here’s how to protect the exterior of your RV during winter storage:

Wash and Wax the RV

Start by giving your RV a thorough cleaning to remove dirt, grime, and any road salt from your last trip. These contaminants can cause corrosion and wear down protective surfaces over time:

  • Use an RV-Specific Cleaner: Choose a cleaning product that’s safe for your RV’s exterior materials. Avoid harsh detergents, as they can strip protective coatings.
  • Wash the Roof and Sides: Clean the roof first, then work your way down to the sides. Pay special attention to hard-to-reach areas, like around windows, awnings, and slide-outs, where grime tends to accumulate.
  • Wax the RV: After washing, apply a high-quality RV wax or paint sealant. Waxing provides an extra layer of protection from moisture, UV rays, and other environmental factors. This helps prevent fading, cracking, and peeling over the winter months.
  • Clean the Awnings: Don’t forget to clean and dry the awnings before retracting them for storage. Mold and mildew can develop on damp awnings, so ensure they’re completely dry before rolling them up.

Inspect Seals and Caulking

Seals and caulking are critical to preventing water leaks, which can be particularly damaging in winter:

  • Check Roof Seals: Inspect all roof seals around vents, antennas, and any other fixtures. Look for cracks, gaps, or areas where the sealant has worn away. Apply new sealant or caulking where needed to ensure a watertight seal.
  • Examine Window and Door Seals: Check the seals around windows, doors, and slide-outs for any signs of wear. Replace or repair any damaged seals to prevent moisture from seeping inside.
  • Slide-Out Seals: If your RV has slide-outs, make sure the seals are in good condition. Use a slide-out seal conditioner to keep them flexible and ensure a proper seal when the slide-outs are retracted for storage.

Cover Your RV

A good RV cover can provide significant protection from snow, ice, and UV rays, helping to prevent damage to your RV’s exterior:

  • Choose a Breathable RV Cover: When selecting an RV cover, make sure it’s breathable to prevent moisture from getting trapped underneath, which can lead to mold and mildew. Opt for one specifically designed for winter use that offers protection against snow and ice.
  • Install the Cover Properly: Once your RV is clean and dry, carefully place the cover over the RV, ensuring it fits snugly without being too tight. Most covers come with adjustable straps to secure them in place, preventing wind from loosening the cover.
  • Avoid Tarping: Never use a plastic tarp as an RV cover. Tarps are not breathable and can trap moisture, leading to condensation, mold, and mildew.

Tire Care

Tires can deteriorate during winter storage if they’re not properly cared for. Cold temperatures can cause tires to lose air pressure, and exposure to the elements can lead to cracking or flat spots:

  • Check Tire Pressure: Inflate your RV’s tires to the manufacturer’s recommended pressure before storage. Cold weather can cause the air pressure to drop, which can damage the tires over time.
  • Use Tire Covers: Tire covers provide protection from UV rays and harsh winter weather, which can dry out and crack the rubber. Covers also help maintain the integrity of the tire’s sidewalls.
  • Consider Jacking Up the RV: If your RV will be stored for an extended period, consider using RV jacks to lift the RV slightly off the ground. This helps to relieve pressure on the tires and prevent flat spots from developing.
  • Park on Plywood or Rubber Mats: If jacking up the RV isn’t an option, park the tires on plywood boards or rubber mats. This provides a barrier between the tires and the cold, hard ground, which can lead to premature wear.

Protect the RV’s Undercarriage

The undercarriage is often overlooked, but it’s susceptible to rust and corrosion if exposed to moisture over the winter:

  • Inspect for Rust: Check the undercarriage for any signs of rust or corrosion. If you find any, clean the affected areas and apply a rust inhibitor or protective coating to prevent further deterioration.
  • Protect the Undercarriage: Some RV owners choose to spray an undercoating on their RV’s chassis to prevent moisture from causing rust during storage. Make sure the undercoating is compatible with RVs and doesn’t trap moisture.

Protect the Exterior Vents and Openings

Small critters like mice or squirrels may see your RV as the perfect winter home. Taking steps to cover exterior vents and openings can prevent unwanted guests:

  • Cover Exterior Vents: Place covers or screens over your RV’s exterior vents, such as furnace vents, fridge vents, and exhaust vents. This keeps pests from entering while still allowing airflow.
  • Seal Gaps and Openings: Inspect the RV’s exterior for any gaps, cracks, or holes that could serve as entry points for pests. Use foam or mesh to seal these openings without disrupting airflow.

Protect the Windows

Protecting your RV windows from frost and condensation can help avoid issues like cracked seals and water damage:

  • Close Blinds or Use Insulated Curtains: If your RV is equipped with blinds or shades, close them to protect the interior from sun exposure. For added insulation, consider using thermal curtains or window covers to help keep the interior of the RV warm and reduce condensation buildup on the windows.
  • Apply Window Insulation Film: If you store your RV in a particularly cold climate, you can apply window insulation film to help prevent frost buildup on the interior of the windows.

Prevent Ice and Snow Build-Up

Accumulation of ice and snow can damage the RV’s roof, slide-outs, and awnings:

  • Remove Snow from the Roof: If you live in an area with heavy snowfall, periodically remove snow from the RV’s roof using a soft brush or broom. Avoid using sharp tools that could damage the roof.
  • Prevent Ice Dams: Ice dams can form along the edges of your RV’s roof, trapping water and causing leaks. Use roof-edge heating cables or regularly remove snow to prevent ice dams from forming.

By taking the time to protect the exterior of your RV before winter storage, you can safeguard it from the harsh effects of snow, ice, and cold temperatures. Following these steps ensures that your RV will look great and function perfectly when it’s time to take it out of storage in the spring

Step 5: Winterize the Engine and Fuel Systems (For Motorhomes)

RV engine

For RV motorhomes, it’s essential to winterize not just the water and plumbing systems but also the engine and fuel systems to ensure they remain in good working condition during the cold months.

Properly winterizing your engine will help prevent issues like corrosion, freezing, and fuel degradation, saving you from expensive repairs when spring arrives.

Here’s how to winterize the engine and fuel systems in your RV:

Change the Oil and Oil Filter

Changing the oil before storing your RV for the winter is a key maintenance step. Old oil can contain contaminants and moisture that may cause engine corrosion over time:

  • Drain the Old Oil: Start by draining the existing oil from the engine while it’s still warm. Warm oil flows more easily and helps flush out any dirt or debris.
  • Replace the Oil Filter: Install a new oil filter to ensure that the engine is protected with clean filtration when it’s restarted in the spring.
  • Fill with Fresh Oil: Refill the engine with fresh, high-quality oil that meets the manufacturer’s specifications for your RV. Using clean oil will help prevent engine wear and corrosion while the RV is in storage.

Add Fuel Stabilizer to the Gas Tank

Fuel can degrade and form deposits over time, especially during long periods of storage. Adding a fuel stabilizer helps prevent the fuel from breaking down and protects the fuel system from corrosion:

  • Fill the Gas Tank: Before adding the stabilizer, fill the gas tank to about 95% capacity. A full tank reduces the amount of air (and moisture) in the tank, which can help prevent condensation from forming.
  • Add the Fuel Stabilizer: Pour the recommended amount of fuel stabilizer into the gas tank based on the product’s instructions. Fuel stabilizer prevents the gas from breaking down into varnish or sludge, which can clog fuel lines and cause poor engine performance.
  • Run the Engine: After adding the stabilizer, run the engine for about 10-15 minutes to circulate the treated fuel throughout the fuel system, including the carburetor or fuel injectors. This ensures that the stabilizer reaches all parts of the engine, providing protection during storage.

Protect the Cooling System (Antifreeze for the Engine)

Your RV’s engine cooling system must be protected from freezing temperatures to avoid cracks and damage to components like the radiator, hoses, and engine block:

  • Check Coolant Levels: Ensure the coolant (antifreeze) level is correct in the radiator and the coolant reservoir.
  • Use the Correct Antifreeze: Make sure you’re using the right type of antifreeze for your RV engine. Most RV engines use a 50/50 mix of antifreeze and water, but check your owner’s manual to confirm the correct ratio.
  • Test the Coolant’s Freeze Protection: If you’re reusing the existing coolant, use a coolant tester to check its freeze protection level. The antifreeze must be able to protect your engine to the lowest expected winter temperatures in your region. If the freeze protection is insufficient, drain the old coolant and replace it with fresh antifreeze.
  • Inspect the Radiator Hoses: Check the radiator hoses for cracks, leaks, or signs of wear. Replace any damaged hoses to prevent them from cracking in cold weather.

Maintain the Transmission and Brake Fluids

Transmission and brake fluids can also be affected by long-term storage, especially in freezing temperatures:

  • Check Transmission Fluid: Before storing your RV, check the transmission fluid level. If the fluid is low or hasn’t been changed in a while, consider servicing the transmission by draining and refilling the fluid. Clean transmission fluid will help protect the internal parts from wear and prevent corrosion.
  • Check Brake Fluid: Verify that the brake fluid level is adequate and top it off if needed. If the brake fluid is dirty or has absorbed moisture, flush and replace it with fresh fluid to avoid brake line corrosion during the winter.

Protect the Engine from Moisture

Moisture can accumulate in the engine and other components during long periods of inactivity, leading to rust or electrical problems:

  • Seal Exhaust Openings: Use specially designed exhaust covers or plastic bags with rubber bands to cover the exhaust pipes. This prevents moisture, pests, and debris from getting into the exhaust system during storage.
  • Cover the Engine Air Intake: For added protection, cover the engine air intake to block moisture from entering the engine. Ensure that any covers you use are easily removable when it’s time to start the RV again.

Store the Engine Batteries

Batteries play a critical role in starting your RV’s engine, so they need proper care during winter storage:

  • Disconnect and Remove Batteries: Disconnect the engine battery, starting with the negative terminal, and then the positive terminal. If possible, remove the battery from the RV and store it in a climate-controlled environment to prevent it from freezing.
  • Use a Trickle Charger: To maintain the battery’s charge during storage, use a trickle charger or battery maintainer. This will keep the battery at an optimal charge level without overcharging it. If you leave the battery in the RV, ensure it’s disconnected and check it periodically to maintain its charge.

Store the RV in a Safe Location

Where you store your RV motorhome during the winter can impact the health of your engine and fuel system:

  • Indoor Storage: If possible, store your RV indoors or under a carport to protect it from the elements. An enclosed storage facility will provide the best protection from snow, ice, and extreme cold.
  • Outdoor Storage: If you must store the RV outside, cover it with a breathable RV cover to shield it from harsh weather. This will help prevent snow and ice from accumulating on the engine compartment and protect the RV’s exterior from freezing temperatures.

Final Checks Before Storage

Before leaving your RV for the winter, it’s important to perform a few final checks:

  • Check the Engine One Last Time: Start the engine and let it run for a few minutes to ensure everything is in working order. This will also circulate fresh oil and treated fuel through the system, giving you peace of mind that the RV is ready for storage.
  • Check Fluid Levels: Double-check that all fluid levels (oil, coolant, transmission, brake) are adequate and that there are no leaks.
  • Inspect for Leaks or Odd Noises: While the engine is running, listen for any unusual noises and inspect for leaks. Address any issues before storing the RV for winter.

By following these steps, you’ll ensure that your RV’s engine and fuel systems are properly winterized and protected from the harsh winter conditions. When spring arrives, you’ll be able to start your RV confidently, knowing it was well cared for during its time in storage.

One of the biggest challenges of winter storage is keeping pests out of your RV.

When temperatures drop, rodents, insects, and other critters often seek warm places to nest, and your RV can become an attractive shelter.

Pests can cause significant damage by chewing through wires, insulation, and fabrics, or leaving droppings and contamination inside the RV. To avoid costly repairs and a messy situation, it’s essential to take preventive steps to keep pests at bay during winter storage.

Seal Exterior Openings

The first line of defense against pests is sealing off any entry points where they might sneak inside your RV:

  • Inspect the Exterior for Gaps and Cracks: Walk around the outside of your RV and inspect it carefully for any small gaps, cracks, or holes that pests could enter. Common entry points include areas around plumbing, wiring, and vents.
  • Seal Openings with Expanding Foam or Caulk: For small gaps, use expanding foam or caulk to seal any cracks or openings. Pay special attention to areas near the undercarriage, around windows, and near utility connections, as these are common points of entry.
  • Use Steel Wool for Larger Gaps: For larger gaps or spaces that need to remain open (like around utility lines), stuff steel wool into the openings. Rodents don’t like chewing through steel wool, making it an effective deterrent.

Protect Exterior Vents and Exhaust Pipes

Exterior vents and exhaust pipes are common entry points for pests seeking warmth:

  • Cover Vents with Screens: Install vent covers or wire mesh screens over your RV’s furnace, refrigerator, and water heater vents. These covers will allow airflow while preventing insects and rodents from entering. You can find pest-proof vent covers designed specifically for RVs at most RV supply stores.
  • Block Exhaust Pipes: Small rodents can crawl into your RV’s exhaust pipes and cause blockages or damage. Use a plastic bag or breathable cover to block off exhaust pipes and prevent critters from climbing in. Just be sure to remove the cover before starting the engine or using any appliances when you take the RV out of storage.

Remove All Food and Scented Items

Food is one of the main reasons pests invade an RV, so it’s crucial to remove anything that might attract them:

  • Empty the Refrigerator and Pantry: Take all food out of the RV, including perishable items, canned goods, dry foods, and snacks. Even non-perishable food can attract pests, so it’s best to store it elsewhere.
  • Wipe Down Cabinets and Counters: Clean out all kitchen cabinets, drawers, and countertops thoroughly. Even small crumbs or food residue can attract insects and rodents.
  • Remove Scented Items: Pests are also attracted to the smell of non-food items like candles, toiletries, and air fresheners. Remove these items, or at least seal them in airtight containers, to prevent curious critters from investigating.

Use Pest Deterrents

In addition to sealing openings and removing food, you can use various deterrents to make your RV less attractive to pests:

  • Natural Repellents: Many RV owners use natural repellents, such as cotton balls soaked in peppermint oil, to deter mice and insects. Place these repellents near potential entry points, around the interior of the RV, and in storage compartments. Other natural deterrents include cinnamon sticks, cloves, and bay leaves, which can be scattered around the RV to ward off pests.
  • Commercial Rodent Repellents: There are several commercial products designed to keep rodents away from your RV, such as ultrasonic devices, rodent-repellent sprays, and scent-based deterrents. These can be placed in areas where rodents are likely to enter, such as near the tires or around the undercarriage.
  • Mothballs or Cedar Blocks: Mothballs can be effective for repelling insects, while cedar blocks or shavings can deter moths and other pests. However, be cautious with mothballs as they can leave a lingering odor, and some people prefer to use natural alternatives like cedar.

Set Traps and Use Preventive Measures

Even with the best preventive efforts, it’s a good idea to set up traps as a backup measure in case any pests do make it inside:

  • Rodent Traps: Place rodent traps around areas where pests are likely to enter, such as near the tires, under the RV, or in storage compartments. If you’re concerned about handling live pests, you can use non-toxic, humane traps that allow you to release the rodents elsewhere.
  • Glue Traps for Insects: Sticky glue traps can help catch insects like spiders or ants that may try to invade your RV during storage. Place these traps in corners, near windows, or anywhere you’ve seen insects before.
  • Inspect Regularly: If possible, check on your RV periodically during the winter. Look for signs of pest activity, such as droppings or gnawed wires. Early detection allows you to address problems before they become severe.

Protect the Undercarriage

The undercarriage of your RV is an often-overlooked area that pests can easily access:

  • Use Rodent Guards Around Tires: Rodents can climb up the tires and make their way into the undercarriage of the RV. To prevent this, use rodent guards or wraps around the base of each tire. You can also place traps or repellents near the tires as an extra precaution.
  • Inspect the Undercarriage for Openings: Look for any holes or gaps in the undercarriage where pests could enter. Seal these openings with foam or wire mesh as needed.

Close Windows, Doors, and Storage Compartments Securely

Make sure all doors, windows, and compartments are tightly sealed to keep pests from finding their way inside:

  • Lock Doors and Windows: Double-check that all doors and windows are securely closed and locked. This includes any roof vents, which should be closed unless you’re using vent covers to provide ventilation.
  • Secure Storage Compartments: Make sure all exterior storage compartments are fully closed and locked. If any compartment doors are damaged or don’t seal properly, repair or replace them before storage.

Use Moisture Absorbers

Moisture can attract pests, especially insects, so keeping the inside of your RV dry is key to pest prevention:

  • Place Moisture Absorbers Inside the RV: Use moisture-absorbing products like DampRid or silica gel packs inside your RV to keep humidity levels low. This helps prevent the growth of mold, mildew, and the damp conditions that attract pests.
  • Open Cupboards and Drawers: Leave interior cupboards, drawers, and closets slightly open to allow air circulation and prevent moisture buildup in enclosed spaces.

By following these pest prevention tips, you can protect your RV from unwanted invaders during the winter months. Taking these precautions will help ensure your RV remains clean, damage-free, and ready for adventure when spring arrives.

Cold temperatures, moisture, and lack of air circulation can lead to problems such as mold, mildew, odors, and even damage to furniture and appliances.

Taking a few preventive steps will ensure your RV’s interior stays clean, dry, and in good condition while it’s in storage. Here’s how to protect your RV’s interior during the winter:

Ventilation and Air Circulation

Proper ventilation is key to preventing moisture buildup inside your RV, which can lead to mold, mildew, and musty odors:

  • Crack Open Roof Vents: If your RV is stored outdoors, consider using vent covers to keep the roof vents cracked open. This allows for airflow while preventing rain, snow, or pests from entering. Ventilation keeps moisture from accumulating, which helps prevent condensation inside the RV.
  • Use Vent Covers: RV-specific vent covers, such as MaxxAir covers, allow you to leave your vents open without exposing the interior to the elements. These covers help air circulate through the RV and prevent moisture buildup.
  • Open Cabinet Doors: Leaving cabinet doors and drawers open slightly can help air circulate more freely throughout the RV. This reduces the chance of dampness collecting in closed-off spaces.

Moisture Control

Moisture is one of the biggest threats to the interior of your RV during winter storage. Excess moisture can lead to mold, mildew, and odors, especially in cold, closed environments:

  • Use Moisture Absorbers: Place moisture absorbers, such as DampRid or silica gel packs, throughout the RV. These products help remove excess moisture from the air, keeping the interior dry. Place them in high-risk areas like bathrooms, kitchens, closets, and storage compartments.
  • Dehumidifier for Indoor Storage: If you’re storing your RV indoors with access to electricity, consider using a small dehumidifier to maintain a dry environment. This is particularly helpful in areas with high humidity or if you’re concerned about excessive moisture.
  • Avoid Fabric-Heavy Items: If possible, remove or cover items like throw pillows, blankets, or fabric upholstery that can easily absorb moisture. Store these items in airtight bags or containers to protect them from dampness.

Protect Furniture and Fabrics

Your RV’s furniture, fabrics, and flooring can suffer damage during long-term storage if not properly protected:

  • Cover Upholstery and Mattresses: Use plastic covers or fabric-safe tarps to protect upholstered furniture, mattresses, and cushions from dust, moisture, and potential pest damage. Covers also help prevent fading caused by sunlight entering through windows.
  • Remove or Roll Up Rugs: If your RV has area rugs or carpets, consider removing or rolling them up to prevent them from trapping moisture or becoming musty during storage. Store them in a dry place or use moisture absorbers in these areas.
  • Use Dryer Sheets or Cedar Blocks: Some RV owners place dryer sheets or cedar blocks in drawers and storage compartments to add a fresh scent and help deter pests while keeping fabrics smelling clean.

Clean and Empty the Refrigerator

Your RV’s refrigerator and freezer need special attention to prevent odors, mold, and mildew from developing over the winter:

  • Empty and Defrost the Refrigerator: Remove all food from the refrigerator and freezer. Clean both thoroughly with a mild detergent or a vinegar solution. If there’s any frost buildup in the freezer, defrost it completely.
  • Leave Doors Ajar: After cleaning, prop open the doors of the refrigerator and freezer to allow air circulation and prevent mold and mildew growth. You can use a towel or other object to keep the doors slightly open. Consider placing an open box of baking soda or a moisture absorber inside to eliminate any lingering odors.
  • Turn Off the Power: Make sure the refrigerator is turned off and unplugged if your RV is connected to shore power. Leaving the refrigerator door open while still running can damage the unit.

Clean and Sanitize the Interior

A thorough cleaning before storage is crucial to maintaining a fresh, welcoming interior when you return in the spring:

  • Vacuum and Sweep: Vacuum carpets, rugs, and upholstery to remove dust, dirt, and crumbs. Sweep and mop hard flooring surfaces to remove any debris that could attract pests or cause wear over time.
  • Wipe Down Surfaces: Use an all-purpose cleaner to wipe down countertops, tables, sinks, and other surfaces. Don’t forget to clean hard-to-reach areas like under the furniture, appliances, and inside cabinets.
  • Clean the Bathroom: Scrub the toilet, sink, and shower thoroughly, and leave a small amount of RV antifreeze in the sink and shower drains to prevent freezing in the P-traps.

Shut Curtains or Use Window Covers

Protecting your RV’s interior from UV damage is just as important as keeping it dry and clean:

  • Close Curtains or Blinds: Close all curtains, blinds, or shades to protect the interior from sunlight exposure. UV rays can cause furniture, fabrics, and flooring to fade over time, even during the winter. Closing curtains also helps prevent passersby from peeking inside your RV.
  • Use Reflective Window Covers: For added insulation and protection, you can use reflective window covers or insulated shades. These covers not only block UV rays but also help maintain a stable temperature inside the RV by preventing heat loss during cold months.

Winterize Appliances

Protecting your RV’s appliances during storage is essential to ensure they work properly when you’re ready to use them again:

  • Unplug Small Appliances: Unplug any small appliances, such as the microwave, coffee maker, or toaster, to protect them from potential power surges or moisture damage. Remove these appliances from the RV if possible.
  • Turn Off the Water Heater: If you haven’t already, turn off the RV’s water heater and ensure it is drained. Leaving the water heater full during the winter can cause serious damage if the water inside freezes.
  • Inspect Large Appliances: Inspect larger appliances, such as the oven, stove, and refrigerator, for any signs of damage or wear. Clean these appliances thoroughly to prevent food debris from attracting pests.

Secure All Doors, Windows, and Compartments

Before leaving your RV for the winter, make sure all doors, windows, and storage compartments are securely closed and locked:

  • Check Window Seals: Inspect the seals around all windows and doors for cracks or gaps. Properly sealed windows prevent drafts and moisture from entering the RV.
  • Lock Doors and Windows: Lock all exterior doors and windows to secure the RV from potential break-ins and to keep cold air and moisture out.
  • Close Storage Compartments: Ensure that all interior and exterior storage compartments are closed and locked to prevent pests from entering or moisture from damaging your stored items.

Remove Valuables

To avoid theft and damage, remove any valuable items from the RV before it goes into storage:

  • Take Electronics and Personal Belongings: Remove any valuable electronics, such as laptops, tablets, and TVs, as well as personal belongings you don’t need in the RV during storage. This minimizes the risk of theft and protects your items from possible damage due to cold or moisture.

By following these steps, you’ll keep your RV’s interior protected from moisture, pests, and cold-weather damage throughout the winter. When you’re ready to take it out of storage, you’ll find a clean, fresh, and well-preserved interior waiting for you, ready to hit the road again.

Step #8: Store Your RV Properly

Covered RV Storage

Choosing the right storage method and location for your RV during the winter is critical to protecting it from the elements, preventing damage, and ensuring it’s ready for the road come spring.

Whether you opt for indoor storage, covered outdoor storage, or simply park it in your driveway, taking the time to store your RV properly can save you money and hassle in the long run. Here’s how to store your RV safely and securely for the winter:

Choose the Right Storage Location

Your choice of storage location will depend on your budget, availability of storage facilities, and the level of protection your RV requires:

  • Indoor Storage (Best Option): Storing your RV in an indoor facility provides the highest level of protection from the elements. Indoor storage shelters your RV from snow, ice, rain, wind, UV rays, and extreme temperatures. It also helps protect against potential pest infestations and vandalism. This option is ideal if you live in an area with harsh winters or if you want maximum protection for your RV investment.
  • Covered Outdoor Storage: If indoor storage is unavailable or too expensive, covered outdoor storage is the next best option. This typically involves parking your RV under a carport, canopy, or in a covered storage facility. A covered structure shields your RV from direct snow, ice, and rain, although it may still be exposed to cold temperatures and wind.
  • Uncovered Outdoor Storage: If your only option is to store your RV outdoors in a driveway or storage lot, you’ll need to take additional precautions to protect it from the elements. While this is the most affordable option, it also leaves your RV vulnerable to winter weather, sun damage, and potential pest problems. Be sure to use an RV cover, tire covers, and other protective measures to safeguard your RV in outdoor storage.

Use an RV Cover for Extra Protection

Whether you’re storing your RV in a covered or uncovered area, an RV-specific cover provides an added layer of protection:

  • Choose a High-Quality RV Cover: Invest in a high-quality, breathable RV cover designed to protect against snow, rain, and UV rays. Avoid plastic tarps, as they can trap moisture underneath and lead to mold and mildew. Look for a cover that’s weather-resistant, durable, and fits your RV snugly.
  • Cover the RV Properly: Once your RV is clean and dry, carefully place the cover over it. Ensure it fits securely around all sides, including over the roof, to prevent moisture from getting in. Most RV covers come with straps or buckles to keep the cover in place, preventing it from flapping in the wind.
  • Use Tire Covers: In addition to covering the RV itself, protect your tires from winter weather by using tire covers. Exposure to UV rays and extreme cold can cause tires to dry out, crack, or lose air pressure over time. Tire covers help extend the life of your RV’s tires and reduce the risk of damage during storage.

Level Your RV

Proper leveling is important when storing your RV, especially if it’s going to be sitting in one spot for an extended period:

  • Use RV Jacks or Blocks: Use leveling jacks or blocks to ensure your RV is parked on a level surface. This prevents unnecessary stress on the chassis and frame, and ensures that your RV is in a stable position throughout the winter.
  • Distribute Weight Evenly: When leveling your RV, make sure the weight is distributed evenly across all points of contact with the ground. Uneven weight distribution can lead to frame warping or tire damage over time.

Protect the Tires

Tires are particularly vulnerable during winter storage, as long periods of inactivity can lead to flat spots, cracking, or loss of air pressure:

  • Inflate Tires to the Correct Pressure: Before storing your RV, check the tire pressure and inflate the tires to the manufacturer’s recommended PSI. Cold temperatures can cause tire pressure to drop, so starting with properly inflated tires helps prevent damage.
  • Relieve Pressure on Tires: If your RV will be stored for a long time, consider using RV jacks or blocks to lift some of the weight off the tires. This helps prevent flat spots from forming due to the tires sitting in one position for an extended period.
  • Park on Tire Pads or Plywood: If you’re storing your RV on asphalt or concrete, park the tires on tire pads or plywood boards. This creates a barrier between the tires and the cold ground, reducing the risk of flat spots and moisture damage.

Keep the RV Locked and Secured

Ensuring your RV is secure while in storage is essential for preventing break-ins, theft, and vandalism:

  • Lock All Doors and Windows: Double-check that all doors, windows, and storage compartments are locked securely. Even if your RV is stored in a secure facility, locking everything up adds an extra layer of protection.
  • Consider a Security System: If your RV is equipped with a security system, activate it before leaving your RV in storage. Motion detectors, cameras, or GPS tracking devices can help deter potential thieves or vandals.
  • Remove Valuable Items: Remove any valuable items, electronics, or personal belongings from the RV to reduce the risk of theft. If you must leave anything inside, store it out of sight in locked cabinets or compartments.

Check on Your RV Periodically

Even after your RV is stored for the winter, it’s a good idea to check on it periodically to ensure everything is in good condition:

  • Inspect for Signs of Damage: If possible, visit your storage site every few weeks or once a month. Check for any signs of damage, leaks, or pest activity. Early detection can help you address small problems before they turn into costly repairs.
  • Check Tire Pressure: Monitor your tire pressure throughout the winter to make sure it hasn’t dropped below the recommended levels. If you notice significant air loss, inflate the tires as needed to maintain proper pressure.
  • Ensure the RV Cover is Secure: High winds or shifting weather conditions can cause the RV cover to loosen or shift. Inspect the cover to make sure it’s still securely in place and hasn’t been damaged by the elements.

Prepare for Spring Removal

When winter is over and it’s time to take your RV out of storage, a few preparatory steps will ensure your RV is ready for travel:

  • Remove the RV Cover: Carefully remove the RV cover and inspect the exterior for any signs of damage or wear that may have occurred during storage.
  • Reconnect the Batteries: If you removed your batteries before storage, reinstall them and check their charge levels. If they’re low, recharge them before reconnecting.
  • Check the Water and Plumbing Systems: If you winterized the water system with antifreeze, flush the system thoroughly before using it. Check for leaks or issues with the plumbing.
  • Inspect the Engine and Tires: For motorhomes, inspect the engine and fuel systems before driving. Check the tire pressure and examine the tires for any signs of wear or cracking.

By taking the time to store your RV properly, you’ll protect it from winter weather, minimize potential damage, and ensure it’s in excellent condition when you’re ready to take it out of storage in the spring. Following these steps will extend the life of your RV and make for a smoother, trouble-free travel season.
