RV Storage Tips from Experienced Owners: Real-World Advice

What Experienced RVers Actually Do

The best storage advice comes from owners who have learned from experience — often from costly mistakes. We compiled the most useful real-world tips from the RV community, organized by category and climate, so you can benefit from years of collective wisdom before your first long-term storage.

Based on our database of 10,431 verified facilities across 48 states, we also know what separates facilities where RVs emerge in perfect condition from those where owners face spring surprises. These tips cover both what you do to your RV and how you choose where to store it.

Before Storage: The Prep That Matters Most

"Mice will find a way in."

This is the most universal piece of advice from experienced RV owners. Steel wool stuffed in every gap, peppermint oil on cotton balls throughout the interior, dryer sheets under seats and in cabinet corners, and commercial rodent deterrents. Several owners report that foam board stuffed tightly into wheel well openings is the most effective barrier. No amount of cleaning after a mouse infestation replaces proper prevention.

Advanced tip: Use expanding foam (Great Stuff or equivalent) on any penetration through the floor or walls that cannot be sealed with steel wool. Mice can chew through almost everything except metal mesh and certain foam compounds. Inspect around water and electrical lines — these are common entry routes that owners overlook.

"Roof inspection every single time."

Re-seal any sealant that shows the slightest cracking before storage. One owner reported $18,000 in delamination damage from a roof seam they had planned to "fix next year." Self-leveling sealant costs $12/tube. Delamination repair costs $5,000–$20,000. (Full prep walkthrough: RV storage preparation guide.)

Use a dedicated RV roof sealant — not hardware store caulk. Dicor self-leveling lap sealant is the community standard for EPDM roofs. For TPO roofs, use a TPO-compatible product. Applying the wrong sealant can actually accelerate deterioration.

"Propane off. All of it."

Turn off the propane at the tank, not just at the appliances. Propane regulators can develop slow leaks. Indoor storage facilities prohibit propane anyway. Some experienced owners go further and disconnect the regulator entirely, capping the tank outlet. This eliminates any possibility of a slow leak filling an enclosed space with gas.

"Fill the fuel tank and add stabilizer."

A common mistake is storing a motorhome with an empty or near-empty fuel tank. Empty tanks allow condensation to form inside, which promotes rust and allows moisture to contaminate the fuel system. Fill the tank at least 90%, add a quality fuel stabilizer (STA-BIL 360° or similar), and run the engine for 10–15 minutes to ensure the stabilized fuel reaches the carburetor and fuel lines.

"Winterize the water system properly — not half-heartedly."

Partially winterized water systems are one of the most expensive spring discoveries. Use an air compressor to blow out each line, then use RV antifreeze (not automotive) in every p-trap: sinks, shower, toilet, and any floor drains. Confirm the water heater bypass valve is in the bypass position before adding antifreeze. One overlooked fitting can mean a burst pipe when temperatures drop.

Tips by RV Type

Class A Motorhomes

The size and weight of Class A units make tire care critical. Use tire covers on all wheels — UV degradation causes sidewall cracking even when mileage is low. Inflate tires to the maximum recommended cold pressure before storage (not while warm). Place boards under tires if stored on asphalt, which can leach oils that degrade rubber. Move the RV forward or back by 2–3 feet at least monthly to prevent flat-spotting on long storage periods. Given the large slideout count on most Class A units, confirm all slides are retracted and seals are lubricated before storage.

Class C Motorhomes

The over-cab sleeping area is a common leak point on Class C units. Inspect the cab-over cap gasket carefully before storage and reseal if needed. Many Class C owners report this area as the first to show water intrusion. The cab-over cap creates a natural place for snow and ice to accumulate, so if storing in cold climates ensure the roof is clear before a freeze cycle.

Fifth Wheels

The pin box area is exposed to the elements and should be covered if possible. Use a pin box cover or wrap with weatherproof material. Slide toppers (awnings over slideouts) collect debris and water — clean them thoroughly before storage and inspect for tears. Fifth wheels have more vulnerable slideout seals than motorhomes because of their greater overall length; inspect every inch of every slide seal before storage.

Travel Trailers

Tongue jack and stabilizer jack pads are essential for trailers stored on soft ground — the jacks can sink over months and create a leveling nightmare in spring. Use Lynx Levelers or similar hard plastic blocks under each jack. For trailers with A-frame trailer tongues, the tongue area can collect water; ensure the drain hole in the tongue tube is unobstructed. Coupler locks are non-negotiable for outdoor storage.

Climate-Specific Storage Tips

Desert and Dry Climates (Southwest, Mountain West)

UV damage is the primary enemy in the desert. Roof sealants dry and crack rapidly under intense sun — inspect and reseal twice yearly in states like Arizona, Nevada, and New Mexico. Rubber roof material benefits from a UV-blocking coating applied annually. Interior fabrics, window seals, and exterior graphics all degrade faster in UV-intense environments.

Tire sidewall cracking happens fast in the desert even without much mileage. Budget for tire replacement every 5–7 years regardless of tread depth. Cover all tires with UV-opaque covers and consider tire dressing (applied to the sidewall surface) to slow oxidation. Keep the interior cool — extreme heat cycles accelerate everything from slide seals to electrical insulation degradation.

Humid and Coastal Climates (Southeast, Gulf Coast, Pacific Northwest)

Moisture is the enemy here. Mold, mildew, and corrosion are your primary threats. Invest in DampRid or a small electric dehumidifier with shore power connection. Coastal RV owners often see accelerated corrosion on metal components — apply corrosion inhibitor (Fluid Film or LPS 3) to exposed metal, slide rail mechanisms, and electrical connections annually.

In Florida and Gulf Coast states, the combination of heat and humidity means even a well-ventilated RV can develop interior mold. Many experienced owners leave the refrigerator door propped open, leave cabinet doors open, and use moisture absorbers in every compartment. Some run the RV's roof air conditioning on a timer for a few hours each week during summer storage to dehumidify the interior.

Cold and Snowy Climates (Midwest, Northeast, Mountain States)

Snow load is the primary structural concern. Most RV roofs are designed for 20–30 lbs per square foot — wet, heavy snow can easily exceed this on a flat roof section. If accessible, brush off accumulations above 4–6 inches. Never use a metal shovel on an RV roof; use a soft broom or plastic shovel. A roof rake used from the ground is safer than climbing on a slippery roof.

Freeze-thaw cycling is especially hard on sealants and plumbing. Re-inspect all plumbing connections in early spring after the first thaw — this is when previously hidden cracks reveal themselves. Battery maintenance is critical in cold climates: a fully charged battery can withstand temperatures to approximately -70°F, while a discharged battery freezes at 32°F. Keep batteries on a maintenance charger connected to shore power, or remove them and store indoors.

During Storage: Things People Forget

"Check monthly, not never."

Several owners recommend monthly check-ins at the storage facility even during off-season. A quick visual walk-around catches developing issues: water leaks through roof, tire problems, battery issues, animal activity, or storm damage. Catching a drip early costs nothing; finding water damage in spring costs plenty. Many experienced owners keep a storage log — noting date, battery voltage, tire pressure, and any observations — which also helps identify trends over time.

"Leave an interior light on a timer."

Some owners leave a small LED lamp connected to a smart plug on a timer to deter theft and provide a visual indicator that the RV has power (indicating the battery is healthy). Smart plugs with energy monitoring also let you track whether the power draw is consistent — a sudden spike might indicate an appliance that was left on or a pest that has chewed a wire.

"Take photos before storage and in spring."

Date-stamped photos document pre-existing damage and provide insurance evidence if damage occurs during storage. Multiple owners have had successful insurance claims specifically because they had clear before-and-after documentation. Photograph all four sides of the exterior, the roof (if accessible), all tires, and any existing damage. Store these photos in a cloud folder that is timestamped and accessible without your primary device.

"Maintain the battery through winter."

Lead-acid and AGM batteries both self-discharge over time. A fully discharged battery in storage can sulfate permanently, requiring replacement. Use a smart battery maintainer (Battery Tender, CTEK) plugged into shore power, or disconnect the battery entirely and store it in a climate-controlled space. Lithium batteries have much lower self-discharge but should still be stored at 50–80% state of charge, not fully charged or fully depleted.

Facility Selection: Hard-Learned Lessons

"Visit at night before signing."

A facility looks very different after dark. Check that lighting is adequate and functional, that cameras have obvious coverage, and that the gate system is responsive. One owner discovered their "24-hour secured" facility had a broken gate that stayed open all night after visiting after 9pm.

"Talk to other customers, not just staff."

Arrive during a weekend morning when other owners are accessing their vehicles. Ask them directly how they like the facility and whether they have had any issues. This is more reliable than Google reviews, which facilities sometimes game. Ask specifically about break-ins, management responsiveness, and whether the facility has changed ownership recently (management changes often accompany a service decline period).

"Check the drainage."

A facility with poor drainage means your RV is parked in standing water after every rain. Look for positive-slope grading, functional drains, and ground that isn't visibly soft or rutted. Gravel lots drain better than asphalt when the asphalt is poorly sloped. One owner described returning to find their trailer sunk several inches into softened gravel after a heavy rain season — the weight of a large RV on concentrated jack points requires solid substrate.

Tips from RV Insurance Claims Data

Based on information shared by RV owners who have filed storage-related insurance claims, the most common covered events during storage are:

1. Hail damage — accounts for a significant portion of storage-period claims; covered storage dramatically reduces this risk
2. Rodent damage — chewed wiring and destroyed insulation; often covered by comprehensive auto insurance but not all policies
3. Theft of external accessories — generators, solar panels, and propane tanks are the most commonly stolen items from outdoor storage
4. Water intrusion / flood — facilities in flood plains or with poor drainage are disproportionately represented in claims
5. Wind damage — awning tears and antenna damage are common in unprotected outdoor storage

Practical implication: if you store outdoors, remove or secure your generator, retract your awning completely, and remove the antenna before storage. Chain the tongue to an anchored receiver if storing a trailer outdoors.

Cost-Saving Tips from Experienced Owners

• Negotiate annual rates: Most facilities offer 10–15% off for annual prepayment. Ask even if it is not advertised.
• Time your move-in strategically: Facilities in northern states often have availability and lower rates in spring after the spring rush. Moving in early (before demand peaks) sometimes yields better rates.
• Ask about off-season specials: Some southern facilities offer reduced rates in summer when demand drops. Conversely, northern facilities may offer winter specials.
• Share a space with a friend: Some facilities allow two smaller vehicles in a single larger space. Confirm this is permitted before attempting.
• Compare total cost, not monthly rate: A facility that is $10/month cheaper but requires a 20-mile detour to reach costs more in time and fuel than the savings.

Seasonal Storage Calendar

Spring (De-Storage)	Remove winterization, test all systems, inspect plumbing for freeze damage, check tire pressure and sidewalls, clean exterior, test all appliances before first trip
Summer (During Use)	Inspect roof sealant mid-season, check slide seals after heavy use, clean and treat awning fabric, maintain tires for heat expansion

Tips for First-Time Long-Term Storage

If this is your first time storing an RV for more than 30 days, here are the things that most first-timers overlook:

• Confirm your auto insurance covers the vehicle while in storage — some policies require notification for extended storage periods
• Do not assume a facility is "secure" just because it has a fence — drive around and look for gaps or unlocked pedestrian gates
• Get the facility's emergency contact number and what to do if you see damage or intrusion outside business hours
• Understand the facility's policy on accessing your vehicle without notice versus scheduled access
• Ask whether the facility performs regular perimeter checks and how often

Reader Q&A: Frequently Asked Community Questions

Q: Can I leave food in the RV during storage?
A: Almost universally no. Even canned goods and packaged snacks attract rodents that chew through packaging. Remove everything edible, including condiments, spices, pet food, and birdseed. Even scented candles and soap bars have been reported to attract mice.

Q: Should I store with slides in or out?
A: Always in. Slide seals compress against the coach body and are designed to protect in the retracted position. Slideouts extended over a long period can cause seal deformation and allow water infiltration. The one exception is if a slideout has a known mechanical problem preventing full retraction — in that case, support the extended slideout with stabilizers and seal the top edge carefully.

Q: What should I do with the holding tanks before storage?
A: Gray tank: flush thoroughly and leave empty. Black tank: thoroughly flush and treat with RV antifreeze if temperatures will drop below freezing. Never store with waste in the black tank — the combination of organic material and enclosed space through warm months creates a biological nightmare that is very difficult to remediate.

Q: How do I store an RV while living abroad?
A: Long-term storage (6+ months) requires a trusted local contact who can visit monthly. Hire a property manager, friend, or family member to perform check-ins. Arrange automatic payment for the storage fee to avoid lapse in coverage. Have a power of attorney in place in case decisions need to be made about vehicle maintenance in your absence. Many owners traveling internationally for extended periods also engage an RV service company to perform a spring check-up before they return.

The One Thing Everyone Agrees On

Visit the facility in person before signing. Read every line of the contract. (Need a checklist? See 20 questions to ask before signing.) Understand the insurance requirements. The cheapest storage facility is not a deal if your RV is damaged or stolen. Compare verified facilities by state. Pay a fair price for a facility with working security, and you will never regret it.
