How to Prepare Your RV and Boat for Long-Term Storage: A Summer & Fall Guide

An RV or boat is more than just a recreational vehicle—it’s a valuable investment and your gateway to freedom, travel, and the great outdoors. But when you’re wrapping up your summer road trips or lake days, it’s essential to prepare these vehicles for storage properly.

Whether you’re storing your RV or boat during an off-season lull, due to HOA regulations, or simply need a break between trips, this guide will help you preserve your vehicle’s condition until you’re ready to hit the road or water again.

Why Long-Term Storage Preparation Matters

Neglecting proper storage can lead to mold, odors, pests, engine issues, and aesthetic damage. From the cabin to the tires, taking a few proactive steps ensures your RV or boat is ready to go the next time you need it—without costly surprises.

1. Control Moisture and Interior Odors

RVs and boats are notorious for trapping moisture and odors, especially when sitting idle for long stretches. Humidity, wet towels, and poor ventilation can turn into mildew and mold.

Interior Preparation Tips:

Remove damp towels, mop up spills, and clean all surfaces.
Empty sinks and drains.
Take out textiles like blankets, pillows, and throws—or vacuum-seal them.
Keep cabinet and fridge doors ajar for ventilation.
Place moisture absorbers (like Damprid) in key areas:
- Under sinks
- Inside closets
- In overhead compartments
- Behind furniture

For boats, it's important to ventilate below-deck spaces and use marine-grade dehumidifiers or desiccant packs in enclosed storage areas. More tips are available in this boat storage guide.

2. Wash and Protect the Exterior

Before storage, it’s important to clean the vehicle thoroughly. Dust, bugs, salt, and sap from road and water exposure can harm paint, trim, and metal components.

Wash and wax the RV or boat.
Clean windows, awnings, and slides.
Inspect seals around windows, doors, and vents—re-caulk if needed.
For boats: scrub hulls clean of algae or mineral build-up.

Consider a professional detailing service to ensure hard-to-reach areas are cleaned and protected.

3. Perform Mechanical Maintenance

While you're not prepping for cold weather, storing a vehicle for any length of time requires basic engine and system maintenance.

Checklist for Engine and System Prep:

Add a fuel stabilizer and run the engine for 10–15 minutes to circulate it.
Change the oil and filter.
Check and top off fluids (coolant, brake, transmission).
Disconnect the battery and store it in a dry, shaded space.
Lubricate all hinges, slide-outs, and locks.
Turn off the gas supply and all onboard appliances.

If storing a boat, remember to:

Drain the bilge and freshwater systems.
Check for fuel system leaks.
Store electronics safely in a dry bag or remove them entirely.

4. Empty the Refrigerator and Remove All Food

Food remnants, even small crumbs, can cause odors and attract pests.

Clean out the fridge and leave the door slightly open.
Wipe down cabinets, drawers, and shelves.
Remove couch cushions or wash any areas where snacks may have fallen.
Clean stovetops and cooking areas to eliminate grease and residue.

5. Keep Pests Out

Rodents and insects are experts at sneaking into stored vehicles.

Block all exterior vents and pipe openings.
Use fine mesh or screens on AC units and roof vents.
Place traps or repellents near common entry points.
For boats, seal hatches and check for loose covers or torn canvas.

6. Drain Non-Essential Water Systems

Even if you’re not concerned about freezing temps, standing water can breed bacteria and cause odors.

Drain freshwater tanks, gray water, and black water tanks.
Flush sinks and showers to ensure lines are clear.
Sanitize the tanks if they won’t be used for a while.

Boats with water systems should also be flushed and dried before storage.

7. Cover Your RV or Boat

Protect your vehicle from UV rays, dirt, bird droppings, and tree sap.

Use a breathable, fitted cover designed for RVs or boats.
Avoid plastic tarps, which trap moisture and cause mildew.
Secure covers tightly to prevent wind movement or damage.

8. Choose the Right Storage Facility

Your backyard or driveway may not offer the protection or space you need for long-term storage. A secure facility gives peace of mind and ensures your RV or boat is protected from theft, vandalism, and weather damage.

What to Look For:

24/7 security and gated access
Oversized or dedicated vehicle parking spots
Flexible lease options for month-to-month or long-term
Covered or enclosed storage
Lighting and wide drive aisles for easy navigation

Storage Rentals of America offers locations nationwide with dedicated boat storage and RV storage spaces up to 60 feet long.

FAQ: Summer & Fall RV/Boat Storage

1. Do I need to disconnect the battery if it's not winter?
Yes. Batteries slowly drain when idle. Disconnecting and storing in a cool, dry place preserves battery life.

2. How do I prevent mold in warm storage environments?
Ventilation and moisture absorbers are key. Keep interior doors open and avoid sealing the vehicle too tightly.

3. Can I access my stored RV or boat during off-season months?
Most storage facilities offer 24/7 or extended access hours. Confirm with the location before storing.

4. How early should I book storage before the season ends?
Spaces fill up fast in late summer and early fall. It’s smart to reserve your spot 4–6 weeks in advance.

5. Are boats safe in uncovered storage?
They can be—if properly cleaned, drained, and covered. However, covered or enclosed storage adds an extra layer of protection.
