The Ultimate Guide to Winterizing Your RV

Drain All Water Systems

One of the most important steps in winterizing your RV is draining all water from the system. Water left in the plumbing can freeze and expand, causing pipes and tanks to burst. Begin by emptying the fresh water tank, followed by the gray and black water tanks. Make sure to flush out any remaining water to avoid unpleasant odors during storage. Next, drain the water heater, ensuring the power is turned off before you begin. Open all faucets and showers to release any trapped water in the lines.

To fully protect your plumbing system, it's recommended to use RV antifreeze. Once the tanks are drained, pour non-toxic RV antifreeze into the fresh water tank and pump it through the water lines. Be sure to run the antifreeze through all faucets, showers, and toilets until it flows out, ensuring every part of the system is protected from freezing temperatures. Taking these steps will keep your RV’s plumbing safe during the coldest months.

Protect the Exterior

The exterior of your RV is constantly exposed to the elements, and winter brings specific challenges like snow, ice, and freezing temperatures. Before storing your RV for the winter, it’s crucial to thoroughly inspect the exterior for any signs of damage or areas that may be vulnerable to leaks. Check the roof, windows, and doors for cracks or worn seals, as even a small crack can let moisture in, leading to water damage and mold. Reseal any problematic areas with a quality RV sealant to keep the interior protected from the elements.

Cleaning the exterior before storage is equally important. Removing dirt, grime, and debris helps prevent any long-term damage caused by corrosive substances that may have built up over time. After cleaning, applying a protective wax coat can further safeguard the RV's finish from harsh winter conditions. For added protection, consider investing in a high-quality RV cover to shield your vehicle from snow and ice buildup. Storing your RV in a covered or indoor facility, if available, provides the best defense against the winter weather, but even a durable cover can make a significant difference.

Prepare the Interior

Just like the exterior, the interior of your RV needs to be properly prepared for winter storage to avoid unpleasant surprises when you’re ready to use it again. Start by giving the interior a thorough cleaning, paying special attention to areas where food may have been stored or spilled. Even small crumbs can attract pests during the winter months, so be sure to wipe down all surfaces, vacuum, and remove any perishables. Leaving the refrigerator door slightly open is also a good idea to prevent mold and odors from developing.

Shut down all appliances and remove batteries from devices like smoke detectors or clocks to preserve battery life. You may also want to unplug any electronics and ensure that the power is turned off to avoid potential electrical issues during storage. Moisture can become a serious problem in an idle RV, leading to mold, mildew, and musty odors. Consider placing moisture absorbers or dehumidifiers throughout the RV to reduce the chance of excess moisture building up inside. These small but essential steps will keep the interior of your RV in top shape throughout the winter months.

Care for the Tires and Chassis

Your RV's tires and chassis are among the most vulnerable parts when the vehicle is in storage for extended periods, especially in cold weather. One of the key steps to protecting your tires is to inflate them to the recommended pressure before storage. Cold temperatures can cause the air in the tires to contract, leading to underinflation, which can result in flat spots if the RV sits in one position for too long. If possible, try to move the RV occasionally to prevent the tires from settling. Alternatively, using jack stands or blocks to raise the RV off the ground can relieve pressure on the tires and help preserve their shape.

The chassis also requires attention before winter storage. Make sure to lubricate any moving parts, such as jacks, hinges, and stabilizers, to prevent them from rusting or seizing up in the cold. Check for signs of corrosion and apply a rust inhibitor if needed, especially if you plan to store the RV in an area where salt or moisture is prevalent. Taking these precautions not only protects your tires and chassis during winter storage but also ensures a smoother and safer start when you're ready to hit the road again.

Check the Electrical System

Before storing your RV for winter, it’s important to properly check and prepare the electrical system to avoid issues when you’re ready to use it again. Begin by disconnecting the RV's main battery to prevent it from draining during long-term storage. Cold weather can shorten the life of your battery, so it’s a good idea to store it in a warm, dry place where it won’t freeze. Additionally, make sure to clean the battery terminals and cables to remove any corrosion that might have built up over time.

You should also unplug your RV from any external power sources and double-check that all appliances are turned off. This step is crucial in avoiding any electrical issues that could arise while the RV is not in use. It’s also wise to inspect all fuses and circuit breakers before storage to ensure everything is in working order. By thoroughly checking and preparing your electrical system, you can avoid unexpected problems and have peace of mind knowing your RV is ready for use once winter passes.

Store Propane Tanks Safely

Propane systems in your RV require special attention before winter storage to ensure they remain safe and functional when you’re ready to hit the road again. Start by turning off all propane appliances and closing the main propane valve. This ensures that no gas remains in the system, which can be a safety hazard during long-term storage. After the propane system is turned off, it’s a good idea to disconnect portable propane tanks from the RV and store them in a well-ventilated, outdoor area. Storing them indoors can be dangerous, especially in the event of a leak, as propane is highly flammable.

In addition to disconnecting and storing the tanks, take a moment to inspect the propane lines and connections for any signs of wear, cracks, or leaks. If you notice anything unusual, have a professional check the system before using it again. It’s also wise to make sure your propane detectors are functioning properly to catch any potential leaks when you return to your RV. Properly storing and maintaining your propane system during the winter months ensures your safety and the system's efficiency when you resume your travels.

Inspect and Cover Vents

Vents are a critical part of your RV’s ventilation system, but they can also be an entry point for pests, debris, and moisture if not properly secured before winter. Before storing your RV, inspect all roof and side vents to ensure they are clean and free of obstructions like dirt, leaves, or bird nests. Clean the vent covers thoroughly to prevent any buildup that could cause issues when your RV is back in use. It’s especially important to check that vents are securely closed to prevent moisture or snow from getting inside, which could lead to water damage and mold growth during storage.

To further protect your RV’s ventilation system, consider installing vent covers or screens. These covers allow airflow while keeping out unwanted pests like mice, birds, or insects, which can cause significant damage if they nest inside your RV during the winter. For added peace of mind, you can use a breathable RV cover that protects the entire vehicle while allowing air to circulate through the vents, helping prevent condensation. Properly inspecting and covering your vents will keep the inside of your RV clean, dry, and pest-free throughout the winter months.

Winterizing Tips for RV Owners in Cold Climates

For RV owners who live in regions that experience particularly harsh winters, additional steps may be necessary to fully protect your vehicle from extreme cold. Adding extra insulation to vulnerable areas, such as water lines, windows, and doors, can help prevent freezing and improve energy efficiency. Installing foam insulation or using RV skirting around the base of the vehicle can significantly reduce the impact of cold air on your plumbing and heating systems. You may also want to consider installing tank heaters to keep your fresh, gray, and black water tanks from freezing during long storage periods in extreme cold climates.

Additionally, if you plan to use your RV occasionally during the winter months, you’ll need to make a few adjustments. Space heaters, heated blankets, and specially designed RV heaters can provide warmth without overloading your RV’s electrical system. It’s important to monitor your propane supply and have a backup heating plan in case your primary system fails. Lastly, regular inspections of your RV during the winter season can help you catch any potential issues early, such as ice buildup or leaks. With these extra precautions, you can be sure your RV stays in great shape, even in the coldest climates.
