Preparing Your RV for Winter: A Comprehensive Checklist

As the days get shorter and the temperature drops, it’s time to start thinking about preparing your RV for winter. Winterizing your RV is crucial not only to protect your investment but also to ensure it’s ready for the next camping season. This comprehensive checklist will guide you through each step of the process, helping you avoid common pitfalls and ensuring your RV remains in top condition.

Why Winterize Your RV?

Winterizing your RV is essential to prevent damage from freezing temperatures, moisture, and pests. According to the Recreational Vehicle Industry Association (RVIA), an estimated 10 million American households own an RV. Proper winterization can save you hundreds or even thousands of dollars in repair costs. Without proper winterization, you risk:

• Frozen and burst pipes
• Water damage
• Mold and mildew growth
• Pest infestations
• Battery and engine problems

Step-by-Step Winterization Checklist

1. Drain and Clean All Water Systems

Water left in your RV’s pipes and tanks can freeze, causing serious damage. Follow these steps to drain and clean your water systems:

• Drain the Freshwater Tank: Open the drain valve and allow all water to flow out.
• Drain the Grey and Black Water Tanks: Empty both tanks at a dump station. Clean the tanks thoroughly with a tank cleaner.
• Drain the Water Heater: Turn off the water heater and let it cool. Open the drain plug and pressure relief valve to drain the water.
• Bypass the Water Heater: Install a water heater bypass kit to prevent antifreeze from entering the heater.
• Blow Out the Water Lines: Use an air compressor to blow out any remaining water from the lines.

2. Add RV Antifreeze

Adding RV antifreeze to your plumbing system will prevent any remaining water from freezing. Here’s how:

• Close All Drain Valves: Make sure all drain valves are closed before adding antifreeze.
• Use a Water Pump Converter Kit: Follow the manufacturer’s instructions to install the kit.
• Run the Antifreeze Through All Faucets: Turn on each faucet (hot and cold) until you see pink antifreeze. Don’t forget the shower, toilet, and outdoor shower.

3. Protect the Exterior

Winter weather can be harsh on your RV’s exterior. Take these steps to protect it:

• Wash and Wax: A thorough wash and wax will protect your RV’s paint and finish.
• Inspect Seals and Seams: Check for any cracks or gaps and reseal as necessary to prevent water intrusion.
• Cover the RV: Use a breathable RV cover to protect against snow, ice, and UV damage.

4. Prepare the Interior

Preparing the interior of your RV is just as important as the exterior. Here’s what you need to do:

• Clean Thoroughly: Clean the entire interior to prevent mold, mildew, and pests.
• Remove Perishables: Take out all food items to avoid attracting pests.
• Protect Against Pests: Use pest repellents and traps to keep rodents and insects at bay.
• Open Cabinets and Drawers: Leave them slightly open to allow for air circulation and prevent moisture buildup.

5. Battery and Engine Care

Proper care of your RV’s battery and engine is crucial for a smooth start next season. Follow these tips:

• Charge and Disconnect the Batteries: Fully charge all batteries and disconnect them to prevent drainage.
• Store Batteries in a Warm Place: If possible, store batteries in a warm, dry location.
• Change the Oil: Perform an oil change to prevent contaminants from sitting in the engine over winter.
• Add Fuel Stabilizer: Add a fuel stabilizer to the gas tank to prevent the fuel from degrading.
• Run the Engine: Run the engine and generator for a few minutes to circulate the stabilizer.

6. Tire Care

Your RV’s tires need special attention to avoid flat spots and dry rot. Here’s how to care for them:

• Inflate Tires to the Recommended Pressure: Check the tire pressure and inflate as needed.
• Use Tire Covers: Protect tires from UV damage with tire covers.
• Consider Tire Blocks or Jacks: Use tire blocks or jacks to take the weight off the tires.

Additional Tips for Winter Storage

Choose the Right Storage Location

Selecting the right storage location can make a big difference in how well your RV weathers the winter. Consider the following:

• Indoor vs. Outdoor Storage: If possible, opt for indoor storage to protect your RV from the elements.
• Security: Choose a storage facility with good security measures to protect against theft and vandalism.
• Accessibility: Ensure the storage location is accessible in case you need to check on your RV during the winter.

Monitor Your RV

Even during storage, it’s important to periodically check on your RV:

• Inspect for Leaks: Check for any signs of leaks or water damage.
• Check Tire Pressure: Ensure tires remain properly inflated.
• Run the Engine and Generator: Run them monthly to keep them in good working order.

Conclusion

Winterizing your RV is an essential part of RV ownership. By following this comprehensive checklist, you can ensure your RV remains in excellent condition and is ready for your next adventure. Remember, the time and effort you invest in winterizing your RV will pay off by preventing costly repairs and prolonging the life of your vehicle. Happy winterizing!
