How to Prepare a Boat or RV for Long-Term Storage

When the boating season ends or travel slows down, knowing how to properly prepare your boat or RV for long-term storage is critical. These large, valuable assets are vulnerable to damage if not stored correctly. Whether you're storing your vehicle for a few months or over a harsh winter, proper prep will protect your investment and extend its life.

At Goodfellas Storage, we provide secure boat and RV parking at our Abbeville, SC, Manning, SC, and St Pauls, NC locations. But storage is just one part of the equation — how you prepare your vehicle before storing it can make all the difference.

Here’s your complete guide to boat and RV storage prep, including maintenance checklists, storage tips, and expert advice.

Why Long-Term Storage Prep Matters

Boats and RVs are exposed to the elements even when parked, especially if you're using uncovered outdoor storage. Moisture, UV rays, pests, and battery drain can cause costly damage over time. By investing a few hours in prep, you’ll prevent:

• Mold, mildew, and pest infestations
• Cracked or faded exteriors from sun damage
• Battery and engine issues from disuse
• Frozen or burst pipes and water systems (in colder climates)

Whether you store your RV or boat at home or at one of our dedicated storage facilities, the preparation steps are largely the same.

Step-by-Step: How to Prepare Your Boat for Long-Term Storage

1. Clean the Boat Inside and Out

Start by giving your boat a thorough wash. Clean the hull, deck, and all surfaces, removing algae, salt, and grime. Vacuum and wipe down the cabin interior to remove food particles and prevent mold.

Pro Tip: A clean boat will be easier to inspect for damage later and less likely to attract pests.

2. Drain Water Systems

Remove all water from tanks, bilges, pumps, and plumbing. Add marine antifreeze if you’re in an area with freezing temperatures. This prevents burst pipes and mold growth.

3. Fuel and Engine Prep

• Fill the fuel tank to prevent condensation
• Add a fuel stabilizer
• Change the engine oil and filter
• Flush the engine with fresh water
• Apply fogging oil to the cylinders if storing over winter

4. Remove Electronics and Valuables

Take out batteries, GPS systems, radios, and anything valuable or temperature-sensitive.

5. Cover It Properly

Use a breathable, UV-resistant boat cover. Avoid tarps that can trap moisture. A good cover protects from debris, sunlight, and animals.

Step-by-Step: How to Prepare Your RV for Long-Term Storage

1. Deep Clean the Interior

Remove all food, clean out the refrigerator, and vacuum thoroughly. Use moisture absorbers to prevent mildew. Leave cabinet doors and the refrigerator slightly open for airflow.

2. Drain Plumbing and Holding Tanks

Flush and sanitize all tanks. Drain fresh water, gray water, and black water tanks. Consider winterizing the system with RV antifreeze if you’re in a cold region.

3. Battery and Electrical

• Disconnect the battery or use a trickle charger
• Turn off breakers and remove fuses
• Close propane valves

4. Tire and Suspension Prep

• Inflate tires to the recommended PSI
• Park on level ground
• Use tire covers to block UV rays
• If possible, move the RV every few weeks or use leveling jacks to avoid flat spots

5. Exterior Maintenance

• Wash and wax the exterior
• Inspect seals around windows and roof vents
• Cover any openings to prevent rodent entry
• Use an RV cover designed for your vehicle type

Climate Considerations

Storage prep varies based on your location:

• Cold climates: Prioritize antifreeze, battery removal, and full winterization
• Hot climates: Focus on UV protection, ventilation, and pest control
• Humid areas: Add dehumidifiers or moisture absorbers to the cabin or cabin areas
