RV winter preparation: Key steps

Indoor or outdoor RV storage: Which one should you choose?

Indoor RV storage protects your vehicle from harsh weather, moisture, and freezing temperatures while ensuring better winter humidity control. It lowers the risk of corrosion, leaks, and water damage caused by snow or ice.

You can leave your RV (motorhome, fifth wheel, travel trailer or tent trailer) with a professional RV storage facility. You can also store it in a garage, warehouse or private building. The space can be heated or unheated—just make sure it is dry and and allows proper air circulation.

Outdoor RV storage is more affordable, especially if you have your own land, driveway or accessible lot. However, you must add extra protection such as an RV tarp, RV cover and proper ventilation. These measures help prevent water infiltration, condensation, and damage to the roof or structure.

Pros and cons of indoor vs. outdoor storage

Should you cover an RV stored outdoors?

Yes. You should always cover your RV when it is stored outdoors for better cold weather protection.

• Small RVs, travel trailers and tent trailers: choose a temporary shelter.
• Large RVs: use breathable tarps—one on top and one underneath—to allow airflow and prevent condensation. RV covers also reduce the risk of water flowing inside the structure.

Important: Remove snow from your RV or its shelter as soon as snow accumulation reaches about 30cm (one foot).

Should you reserve your storage spot early? And how much does it cost?

Yes, reserve your storage space as early as possible. Heated or indoor winter RV storage spots fill up quickly, and early reservations often get better pricing.

The cost of RV storage varies depending on:

• the size of your RV
• the type of storage (heated indoor, unheated indoor, outdoor)
• your region

When should you winterize an RV?

The best time to winterize your RV is before temperatures drop below freezing.

This protects the plumbing system, tanks and any components sensitive to cold air.

How to prepare the inside of an RV for winter

Some specialized companies offer RV maintenance services in winter, but you can do it yourself. The process is the same for travel trailers or fifth wheels equipped with similar systems.

What should you remove from the RV before storage?

Before storing your RV for winter, remove the following:

• All perishable and nonperishable food
• Cushions, curtains and removable fabrics that may absorb humidity
• Propane tank cylinders, if required by your insurer or storage provider
• Batteries and fragile items that could be damaged by moisture or freezing

What are the essential steps to prepare the inside of your RV for winter?

Once your RV is emptied, follow these steps to properly prepare the interior:

• Clean the RV thoroughly—cabinets, garbage bins… check every corner.
• Inspect and redo seals and caulking if needed.
• Drain and purge all tanks and pipes (shower, sink, dishwasher, washer, water heater and drains).
• Add nontoxic RV antifreeze. Do this after the purge—water and antifreeze must not be mixed.
• Turn off electrical power and close the propane supply.
• Close blinds to help stabilize indoor temperature.
• Leave bathroom doors, fridge, freezer and cabinet doors open.

Tip: Always check your owner’s manual. Questions? CAA-Quebec’s Mobility Advisory Services can help.

Mechanical maintenance for motorhomes: What to do before winter

Here are the mechanical tasks required to winterize a motorized RV:

• Perform an oil change.
• Inflate tires according to the manufacturer’s recommendations and cover the wheels to protect them from UV rays.
• Lift the RV and place it on blocks.
• Check all fluid levels.
• Fill the fuel tank and add a fuel stabilizer.

Should you disconnect or remove the RV battery for winter?

Yes. Remove and store the RV battery in a dry, temperate place before long-term storage. Avoid cold surfaces like concrete, and recharge it every 4 to 6 weeks.

How to keep rodents out of a stored RV

To prevent rodents in your RV during winter, follow these simple tips:

• Remove food and items that may attract animals.
• Use repellents, traps or mothballs inside and around the RV.
• Seal openings with steel wool, aluminum or foam—without blocking ventilation.

What does RV insurance cover during storage?

Your RV is protected against non-collision damage, such as:

• a branch or tree falling on the vehicle
• flooding
• fire
• theft
• vandalism

For extra protection once you're back on the road, make sure you have your CAA-Quebec membership. The RV Option gives you Roadside Assistance tailored to your vehicle, which is perfect for RV owners seeking peace of mind.

Can you pause RV insurance payments during storage?

Most of the time, no. Many insurers, including CAA-Quebec, do not offer credits for storage because this protection is already included in the annual premium.

If your insurer allows a suspension, make sure:

• not to move the RV
• to reactivate coverage before hitting the road

RV storage: What you need to know

Storing your RV for the winter months means protecting it in a safe, weather-resistant location to prevent damage from snow, ice, humidity and temperature changes. Whether you choose indoor or outdoor RV storage, make sure the space is dry, secure and properly ventilated. Good storage practises help maintain your RV’s condition, reduce wear on key components and ensure that your vehicle is ready to hit the road again when camping season returns.

Storing your RV can also be done with the Société de l’assurance automobile du Québec (SAAQ). It allows you to temporarily suspend your RV’s registration in order to save money. However, this option is not available for trailers and tent trailers. Their registration is paid only once, as long as you remain the owner.
