How To Properly Winterize Your RV: Essential Steps and Expert Tips

Draining and Protecting Your RV’s Water System

An essential part of winterizing your RV is to drain and protect the water system from freezing temperatures, which can cause pipes to burst. Follow these steps to safeguard your water system:

1. Drain Fresh Water and Waste Tanks: Empty the fresh water, gray water, and black water tanks. Ensure all tanks are drained and valve caps securely fastened.

2. Bypass the Water Heater: Turn the bypass valve to prevent any antifreeze from entering the hot water heater.

3. Drain Water Lines: Open all faucets and flush the toilet to ensure no water remains in the lines. Don’t forget exterior faucets, showerheads, and low-point drains.

4. Use RV Antifreeze: Using non-toxic RV antifreeze, pump the solution through the water lines using the RV’s water pump or an external hand pump. Open all faucets until antifreeze appears, and close them afterward. Pour some antifreeze into drains and toilets to protect the plumbing and valves.

Protecting Your RV’s Exterior

Winter weather can wreak havoc on an RV’s exterior. Take these steps to shield your RV’s exterior from the elements:

1. Inspect Roof and Seals: Examine your RV’s roof for any damage, cracks, or potential leaks and reseal as necessary. Don’t forget to inspect around vents, air conditioning units, and other openings.

2. Clean the Exterior: Thoroughly wash and wax your RV’s exterior, including all compartments and awnings, to protect it from dirt, moisture, and UV damage.

3. Protect Tires: Inflate tires to the manufacturer’s recommended pressure and use tire covers to protect them from UV radiation and other weather-related damage.

4. Use an RV Cover: Invest in a high-quality RV cover that fits your RV well and provides protection from snow, ice, and UV rays.

Preparing Your RV’s Interior for Storage

Attention to your RV’s interior is just as crucial during winterizing, ensuring a pleasant and welcoming environment upon your return:

1. Clean Cabinets and Storage Areas: Remove food, toiletries, and other perishable items that may attract pests. Thoroughly clean and sanitize all surfaces to prevent mold or mildew growth.

2. Close Vents and Secure Windows: Ensure all vents are closed and windows sealed, preventing moisture and pests from entering your RV.

3. Use Moisture Absorbers: Strategically place moisture-absorbing products or desiccants throughout your RV to prevent excess humidity and mold growth.

4. Protect Upholstery and Fabrics: Vacuum and clean upholstery, curtains, and mattresses. If possible, remove and store them indoors to avoid mildew and damage from moisture.

Safeguarding Your RV’s Electrical and Mechanical Systems

Your RV’s electrical and mechanical systems also need protection during winter storage:

1. Engine and Generator Maintenance: Change the oil and oil filter in the engine and generator. Top off your fuel tank and add a fuel stabilizer to help prevent condensation.

2. Battery Storage: Disconnect and remove your RV battery, storing it in a cool and dry location. Attach a battery maintainer to keep the battery charged throughout the winter months.

3. Pest Prevention: Seal any openings where rodents or insects may enter your RV. Consider using natural repellents, like peppermint essential oil or mothballs, to deter pests. Inspect your RV regularly during storage for signs of pest activity.
