11 things park model RV owners always forget to winterize and regret later

As winter approaches, park model RV owners need to take extra precautions to safeguard their mobile homes from the harsh elements. While many are diligent in their preparations, there are often critical areas that get overlooked, leading to costly repairs and unnecessary stress. Ensuring every part of the RV is winterized can make the difference between a worry-free winter and a season filled with regrets.

In this article, we'll explore the 11 most commonly forgotten areas that need attention during the winterization process. By addressing these often-overlooked components, park model RV owners can prevent damage and ensure their RV is ready for use come spring.

One of the first things that RV owners often forget is the main water line and the hidden low-point drains. These components are crucial in ensuring that all water is completely drained from the system to prevent freezing and bursting. Owners should locate all low-point drains, which are typically found at the lowest part of the water system, and open them to allow any remaining water to flow out.

It's advised to use compressed air, at a pressure of 30-40 psi, to blow out any residual water from the lines after the drains have been opened. This step is crucial because even a small amount of trapped water can expand and cause significant damage when it freezes.

The water heater tank in an RV is another component that often gets overlooked. It's important to drain the tank completely and bypass it if possible, using the installed bypass valve. This prevents antifreeze from entering the tank, which can lead to contamination and damage.

Additionally, check the anode rod, which is designed to prevent tank corrosion. If the rod is more than 75% depleted, it should be replaced. Properly maintaining the water heater not only prepares it for winter but also extends its longevity.

Interior plumbing fixtures, such as P-traps and toilets, are prone to freezing and bursting if not winterized properly. After draining the water lines, it's essential to add RV antifreeze to all P-traps and toilets. Typically, one cup of antifreeze per fixture is sufficient to prevent freezing.

Ensure that the antifreeze is circulated through all faucets and showerheads by running them until the pink color of the antifreeze is visible. This will protect the entire plumbing system from freezing damage.

Exterior showers and hose bibs are easy to forget, but they are just as vulnerable to freezing temperatures as the interior plumbing. These should be drained and filled with antifreeze to prevent any water left inside from expanding and causing cracks.

Utility connections, such as the city water inlet, should also be winterized. Disconnect any hoses and allow them to drain completely before storing them. It's a good idea to cover these connections with insulated caps to offer additional protection against the cold.

Holding tanks and dump valves need to be thoroughly emptied and cleaned before winter sets in. Use a tank cleaner or a solution of bleach and water to sanitize the tanks, ensuring they are completely free of waste.

After cleaning, add a few gallons of RV antifreeze to each tank to protect the valves and seals from freezing. Sewer hoses should be drained, cleaned, and stored in a dry place to prevent cracking in cold temperatures.

The roof is often neglected during winterization, yet it's vital to inspect it for any leaks or damage. Apply a high-quality sealant to any potential problem areas to prevent water ingress.

Slide seals and window weatherstripping should also be checked for wear and tear. Applying a silicone-based conditioner to these seals helps maintain their pliability and effectiveness in keeping out moisture and cold air.

Adding skirting around the base of the RV is a great way to reduce cold air penetration. Proper skirting can help maintain a stable temperature underneath the unit and protect the plumbing from freezing temperatures.

Ensure that underbelly insulation is intact and that any exposed piping is adequately insulated. Foam pipe insulation or heat tape can be used to prevent pipes from freezing and bursting during frigid weather.

Appliances with water lines, such as refrigerators with ice makers, washers, and dishwashers, require special attention. Disconnect and drain any water lines feeding these appliances to prevent freezing damage.

For ice makers, it's crucial to turn off the water supply and run a cycle to ensure that all water is expelled from the system. Consult the appliance manuals for specific winterization procedures as they can vary by model.

Batteries should be fully charged and disconnected to prevent them from draining over the winter. Store them in a cool, dry place to prolong their lifespan.

Inspect electrical systems for any signs of wear or damage. Shore power cords should be checked for frays and stored properly to avoid damage from extreme cold. If the RV will remain connected to power, consider using a surge protector to guard against electrical issues.

Propane systems need to be checked and secured before winter. Ensure that all propane tanks are turned off and disconnected if the RV will not be in use.

Inspect regulators and furnace intakes for any blockages or damage. Clean the furnace intake to ensure it operates efficiently when needed. Propane systems should be tested for leaks using a soapy water solution on connections.

Moisture control inside the RV is crucial to prevent mold and mildew. Use moisture absorbers or dehumidifiers to keep humidity levels in check.

Soft goods, such as curtains, bedding, and cushions, should be cleaned and stored in vacuum-sealed bags to protect them from moisture and pests. Additionally, take precautions against pests by sealing any potential entry points and using deterrents as necessary.
