Storing an RV isn’t like parking a car and tossing a cover over it. RVs are part vehicle, part home, and part investment—so when storage is done wrong, the damage can be expensive, annoying, and sometimes irreversible. The good news: most storage-related issues come from a handful of common mistakes, and they’re all avoidable with a little planning.
Below are the most frequent RV storage mistakes people make—and exactly how to dodge them—so your rig is ready to roll when adventure calls.
Mistake #1: Skipping a Full Clean (Inside and Out)
It’s tempting to park your RV “as-is,” especially after a long trip. But leaving grime, bugs, road salt, or food crumbs can turn into bigger problems while the RV sits.
What can go wrong:
- Mold and mildew from moisture trapped inside
- Pest infestations attracted by food smells
- Stained seals and paint deterioration from acidic bug splatter or salt
How to avoid it:
- Wash and dry the exterior thoroughly, including the roof if accessible.
- Clean the interior like you’re moving out: remove all food, wipe surfaces, and vacuum.
- Leave cabinet doors slightly ajar (if safe to do so) to improve airflow.
- Use moisture absorbers in humid months.
Mistake #2: Not Winterizing Properly (Especially in Wisconsin)
If you store an RV through cold weather without winterizing, you’re basically gambling with your plumbing system. In Wisconsin, freezing temperatures can crack pipes, damage pumps, and ruin the water heater.
What can go wrong:
- Burst water lines
- Cracked tanks or fittings
- A springtime repair bill that hurts more than winter ever did
How to avoid it:
- Drain fresh, gray, and black tanks completely.
- Bypass and drain the water heater.
- Blow out the lines and/or use RV antifreeze as recommended by your RV manufacturer.
- Don’t forget low-point drains and exterior showers.
Mistake #3: Parking with Low Tire Pressure (or Ignoring Tires Entirely)
Tires don’t like sitting still for months—especially under heavy loads. RV tires can develop flat spots, sidewall cracking, or slow leaks when neglected.
What can go wrong:
- Flat-spotted tires that vibrate on the highway
- Sidewall damage and dry rot
- Premature tire replacement
How to avoid it:
- Inflate tires to the storage pressure recommended for your RV.
- Use tire covers to protect from UV damage (even in storage, sunlight matters).
- If storing long-term, consider using leveling blocks or pads to reduce stress.
- Move the RV slightly every few weeks if possible (or rotate tire contact point).
Mistake #4: Leaving the Battery Connected (and Hoping for the Best)
Many RV owners discover in spring that their batteries are dead—or worse, damaged. Batteries slowly discharge over time, and some RV systems draw power even when “off.”
What can go wrong:
- Dead batteries that won’t hold a charge
- Corrosion on terminals
- Shortened battery lifespan
How to avoid it:
- Disconnect the battery or use a battery cutoff switch.
- Store batteries in a maintained state using a smart trickle charger (if allowed/safe).
- Clean terminals and check water levels (for lead-acid batteries).
- If you store where power access is limited, just disconnecting can help a lot.
Mistake #5: “Good Enough” Covers That Trap Moisture
Covers can be helpful—but the wrong cover can do more harm than good. Cheap tarps or non-breathable covers can trap moisture, rubbing paint and encouraging mildew.
What can go wrong:
- Mold growth underneath the cover
- Scratched paint from flapping material
- Condensation damage in changing temperatures
How to avoid it:
- Use a breathable RV-specific cover designed for your RV size and shape.
- Ensure it’s secured, padded at sharp edges, and not overly tight.
- If you’re storing indoors, you may not need a full cover at all—another reason indoor storage can be a smart move.
Mistake #6: Not Protecting Against Rodents and Critters
RVs are cozy. Unfortunately, mice agree. A stored RV can become a winter condo for pests unless you block entry points and remove “invitations.”
What can go wrong:
- Chewed wiring and insulation
- Nesting in vents, engine bays, and compartments
- Unpleasant odors and sanitation issues
How to avoid it:
- Seal obvious entry points (steel wool + foam works for gaps).
- Cover vents appropriately with RV-safe screens.
- Remove all food and scented items.
- Set traps or deterrents (peppermint oil can help, but real prevention is sealing + cleanliness).
Mistake #7: Choosing the Wrong Storage Facility
This is the big one. You can do everything right, but if your storage environment is poor—tight access, no security, bad drainage, or rough surfaces—you’re starting at a disadvantage.
What can go wrong:
- Weather exposure and faster exterior wear
- Higher risk of theft or vandalism
- Difficult maneuvering that leads to scratches and dents
- Uneven ground causing stress on tires and suspension
How to avoid it:
Choose a facility that makes RV storage feel like it was designed for RVs—not an afterthought.

A Simple RV Storage Checklist (Save This)
Before you lock up and walk away:
- Clean interior/exterior fully
- Winterize plumbing (if storing through freezing temps)
- Inflate tires and cover them
- Disconnect or maintain batteries
- Remove food and moisture sources
- Block pest entry points
- Use a breathable cover if needed
- Store at a secure, RV-friendly facility like Apple Mini Storage

FAQ
1. How do I prepare my RV for long-term storage?
Clean it inside and out, remove all food, empty trash, turn off appliances, disconnect the battery (or use a maintainer), check tire pressure, and cover vents/openings to deter pests. If storing through winter, fully winterize the plumbing system.
2. Do I need to winterize my RV in Wisconsin?
Yes—if temperatures can drop below freezing while it’s in storage. Winterizing helps prevent burst pipes, cracked fittings, and water heater damage by draining the system and protecting lines with air blow-out and/or RV antifreeze.
3. Should I disconnect my RV battery during storage?
Usually, yes. Many RVs have small “parasitic draws” even when switched off. Disconnecting prevents deep discharge, which can shorten battery life. For longer storage, a smart battery maintainer is helpful if safe and allowed.
4. What should I do about my RV tires while it’s stored?
Inflate to the manufacturer’s recommended storage pressure, use tire covers to block UV, and park on a solid surface or pads to reduce stress. For very long storage, moving the RV slightly or rotating tires can help prevent flat spotting.
5. Is it better to store an RV indoors or outdoors?
Indoor storage offers the most protection from sun, snow, hail, and moisture—helping preserve paint, seals, and roof materials. Outdoor storage can still work well if you use a breathable cover, maintain seals, and choose a secure facility.
6. How can I prevent mice and pests from getting into my RV?
Remove all food and scented items, clean thoroughly, seal entry gaps (especially around plumbing/wiring), install vent screens, and consider traps or deterrents. The biggest wins are cleanliness and sealing access points.
7. Should I cover my RV in storage?
If outdoors, a breathable RV-specific cover is recommended. Avoid cheap tarps that trap moisture and rub the finish. If indoors, a full cover may be optional—many owners just use tire covers and windshield protection.
8. What fluids should I check before storing my RV?
Top off fuel (and add a fuel stabilizer for gasoline engines), check oil and coolant levels, and ensure the propane is shut off. For motorhomes, follow the chassis manufacturer’s storage guidance for engine and generator exercise.
9. How often should I inspect my RV while it’s in storage?
A quick check every few weeks is ideal. Look for leaks, signs of pests, low tire pressure, battery condition, and any damage to covers or seals—catching small problems early saves major repair costs.
10. What should I look for in an RV storage facility in Wisconsin?
Prioritize security, clean and accessible drive lanes, good drainage, and storage options that fit your RV size. Many owners choose Apple Mini Storage, known as a leading name in self-storage solutions in Wisconsin, for a straightforward storage experience and peace of mind.
