Why Indoor Winter Storage for RVs is a Game Changer

Think of indoor RV storage like tucking your camper into a warm, safe bed for the winter. When you leave your RV parked outside during the colder months, it’s vulnerable to a lot of potential problems. Snow piling up on the roof can add immense pressure, potentially causing leaks or structural damage. Freezing temperatures can freeze water left in pipes, leading to bursting pipes—a repair that’s both expensive and a major headache.

Then there’s the sun. Even in winter, UV rays can degrade seals, tires, and the exterior paintwork over time. And let’s not forget about critters! Squirrels, mice, and other small animals can find their way into your RV, causing damage to wiring, insulation, and upholstery as they make a nest. Keeping your RV indoors dramatically reduces these risks.

Investing in indoor storage means peace of mind. You won’t have to worry about unexpected damage when spring rolls around. Instead, you can look forward to hitting the road with confidence, knowing your RV has been well looked after. It’s a proactive approach that saves both stress and money in the long run.

Choosing the Right Indoor Storage Facility

Finding the perfect spot for your RV to hibernate is crucial. Not all indoor storage facilities are created equal, and the best choice for you will depend on your needs and budget. When you’re scouting for a place, keep these important factors in mind:

Security Features: Look for facilities with good lighting, a secure gate system (keypad entry, card access), and surveillance cameras. Knowing your RV is safe from theft or unauthorized access is paramount.
Climate Control (or lack thereof): While “heated” storage sounds ideal, it’s not always necessary and can significantly increase costs. For most RVs, a dry, protected space is sufficient. If you’re in an area with extreme temperature fluctuations, a well-ventilated, but unheated building is often enough to prevent major damage.
Accessibility: Consider how easy it will be to get your RV in and out of the storage unit. Are the aisles wide enough? Are there any tricky maneuvers required? How often can you access your RV if needed? Some facilities have 24/7 access, while others have limited hours.
Size and Type of Unit: Ensure the storage unit is large enough for your RV, including any accessories you might be storing with it. Units can range from individual bays to large warehouse-style spaces. Higher ceilings are a plus.
Insurance: Check if the storage facility offers any insurance or if you’ll need to rely on your own RV insurance. Understand what’s covered and what’s not.
Cleanliness and Maintenance: A well-maintained facility generally indicates better care for stored vehicles. Look for a clean environment free of pests or excessive dust.
Cost: Prices vary widely based on location, size, and amenities. Get quotes from several places and compare them. Don’t just go for the cheapest option; evaluate the overall value.

Many storage facilities cater specifically to RVs and offer specialized bays designed to accommodate their size and shape. You might also find options in self-storage units or large warehouses, but ensure they can comfortably fit your vehicle. Always visit potential locations in person if possible to get a true feel for the environment.

Essential Steps for Preparing Your RV for Indoor Storage

Before you tuck your RV away for its winter nap, a thorough preparation process is key. This isn’t just about cleaning; it’s about protecting all the systems and surfaces from the potential ravages of time and being stationary. Let’s break down what you need to do:

1. Thorough Cleaning Inside and Out

Start with a clean slate! This step is not only for aesthetics but also to prevent mold, mildew, and to deter pests.

Exterior Wash and Wax: Give your RV a good wash to remove dirt, grime, and road salt. A fresh coat of wax adds a protective layer against dust and moisture. Pay attention to the roof, as old sealants can crack and allow water ingress.
Interior Deep Clean: Remove all food items, trash, and anything that could attract pests or spoil. Wash all surfaces, including countertops, sinks, and the refrigerator. Clean upholstery and carpets, and ensure everything is dry before storing.
Empty and Clean Tanks: Thoroughly empty and flush your gray and black water tanks. Leave the drain valves open if recommended by your RV manufacturer to allow for ventilation and prevent sealing issues. Some owners prefer to leave a small amount of RV antifreeze in the tanks to prevent them from freezing, but this can be messy and isn’t always necessary for indoor storage. Always follow your RV manual’s recommendations.

2. Winterizing Your RV’s Plumbing System

This is arguably the most critical step to prevent costly freeze damage. Winterizing ensures all water lines, pumps, and fixtures are protected from freezing temperatures.

Drain All Water: Open all faucets (hot and cold), flush the toilet, and drain the water heater. Open the low-point drains to remove as much water as possible from the system. For the water heater, bypass it using the provided valves if you plan to use RV antifreeze to avoid filling the heater tank itself.
Introduce RV Antifreeze: The easiest way to do this is by using the RV’s onboard water pump. Connect a short piece of hose to the water pump’s intake and place the other end into a jug of non-toxic RV antifreeze (use the pink stuff, not automotive antifreeze). Turn on the pump and open each faucet one by one until pink antifreeze flows out. Don’t forget the showerhead and outdoor shower. Flush the toilet until pink antifreeze is visible in the bowl.
Alternative (Non-Toxic): If you’re uncomfortable with antifreeze or want a more environmentally friendly approach, some RV owners opt to thoroughly blow out the lines with compressed air. Ensure the pressure is kept low (around 30-40 PSI) to avoid damaging seals in your plumbing. You’ll need an air compressor with the correct adapter. Follow strict safety guidelines when using compressed air.
Protect P-Traps: Pour a small amount of RV antifreeze or a non-toxic alternative into sink and shower drains to keep the P-traps from freezing and cracking.

3. Battery Care

Your RV batteries need attention to ensure they’re ready for your next adventure.

Fully Charge the Batteries: Before storing, ensure your RV’s batteries are fully charged. A good battery charger or trickle charger can help maintain their charge over the winter.
Disconnect Batteries: It’s often recommended to disconnect at least the negative battery cable to prevent parasitic drain from appliances that might still draw power. If you have multiple batteries, consider removing them entirely and storing them in a cool, dry place (not on concrete, as it can discharge them faster) where they can be periodically checked and charged. Check your owner’s manual for specific battery storage recommendations.

4. Tire Protection

Tires can develop flat spots if they sit in the same position for an extended period.

Inflate to Max Pressure: Over-inflate your RV tires to the maximum pressure listed on the sidewall. This helps them maintain their shape.
Use Tire Covers or Blocks: Place RV tire savers or chocks under the tires to lift them slightly off the ground and distribute the weight. This prevents flat spots from forming.
Consider Moving the RV: If your storage allows, periodically moving the RV a few inches can also help prevent flat spots.

5. Pest Prevention

Keeping unwanted visitors out is crucial to prevent damage.

Seal Entry Points: Check for any small holes or gaps around the RV’s exterior where pests might enter, such as around plumbing or electrical hookups. Seal them with steel wool (which they don’t like to chew through) and caulk.
Use Repellents: Place mothballs, dryer sheets, or commercial pest deterrents in cabinets, drawers, and under the RV. Consider natural repellents like peppermint oil.
Cleanliness is Key: Ensure there are absolutely no food crumbs or spills left inside. Even a small amount can attract pests.

6. Interior Protection

Protect surfaces and materials from damage and deterioration.

Cover Windows: Use blinds, curtains, or reflective sunshades to block UV rays and prevent fading of upholstery or wood finishes.
Protect Upholstery: If you have leather or sensitive fabric, consider covering them to protect from dust and potential moisture.
Moisture Control: Place moisture absorbers (like DampRid) in various locations inside the RV, especially in enclosed spaces like bathrooms and closets. Empty and replace them as needed.

RV Coverings: To Use or Not to Use Indoors?

When storing your RV indoors, the need for a full RV cover is greatly reduced. The primary purpose of an RV cover when stored outdoors is to protect it from UV rays, rain, snow, bird droppings, and tree sap. An indoor environment already provides shelter from these elements.

However, some RV owners still prefer to use a cover, even indoors. Here are a few reasons and considerations:

Dust Protection: Indoor facilities, especially older warehouses or garages, can accumulate dust. A cover can prevent this dust from settling on furniture, appliances, and surfaces, making it easier to clean when you retrieve your RV.
Scratch Prevention: If there’s a risk of accidental bumps or scratches from other stored items or during movement within the facility, a cover can offer an extra layer of protection.
Maintaining That “New” Feel: Some owners simply like the idea of keeping their RV fully protected, almost like wrapping a precious gift, to maintain its pristine condition.
Not a Substitute for Winterizing: It’s crucial to remember that an RV cover, indoors or out, does absolutely nothing to protect the water systems from freezing. Proper winterizing is still essential.

If you choose to use a cover indoors, opt for a breathable fabric. Avoid vinyl or plastic covers that can trap moisture, which could lead to mold or mildew issues inside the RV.

What About Generator and Fuel?

Taking care of fuel systems and generators is vital to ensure they function correctly when you’re ready to use them next season.

Generator: If your RV has a generator, you’ll want to run it periodically (monthly, if possible) for about 15-20 minutes under load with a stabilizer in the fuel. This keeps the engine lubricated, the fuel fresh, and prevents seals from drying out. If you can’t run it, ensure you follow the manufacturer’s instructions for long-term storage, which often involves draining the fuel or using a specific fuel stabilizer.
Gasoline Engines: For gasoline-powered RVs, it’s generally recommended to fill the fuel tank completely before storage and add a quality fuel stabilizer. This helps prevent condensation from forming inside the tank, which can lead to rust and water contamination.
Diesel Engines: Storing diesel RVs can be a bit different. Unlike gasoline, diesel fuel can degrade and develop microbial contamination over time. Some experts recommend filling the tank completely with treated diesel fuel, while others suggest leaving it about half to three-quarters full. Consult your RV’s manual or a diesel mechanic for the best approach based on your specific rig.

Running the engine occasionally (if the RV is on your property and you can start it) for about 15-20 minutes can also help keep internal components lubricated. Make sure to do this in a well-ventilated area.
