RV Storage Preparation Checklist

Properly preparing your RV for storage—whether for the winter season or just a few months between trips—helps prevent leaks, pest infestations, battery failures, and other issues that can develop when an RV sits unused. A little preparation before storage can save you from expensive repairs and headaches when you're ready to hit the road again.

Why Storage Preparation Matters

RVs are designed to be used regularly. When they sit for months without power, airflow, or attention, problems can develop. Batteries drain and sulfate, tires develop flat spots or weather cracks, and seals dry out. Rodents and insects can find their way inside through vents or gaps and cause significant damage. Water left in the plumbing system can freeze and crack pipes or tanks. Moisture buildup can lead to mold and mildew. Taking the time to properly prepare your RV for storage minimizes these risks and ensures it's ready to go when you are.

Exterior Preparation Steps

Start by thoroughly washing and waxing the exterior to protect the finish. Inspect the roof and reseal any cracks or gaps around vents, AC units, and skylights. Check the awning for mold or damage and ensure it's fully retracted and secured. Cover the RV with a breathable cover if you're storing it outdoors—this protects the roof and sidewalls from UV damage and debris. If you're storing it uncovered, consider placing plywood under the tires to prevent flat spots and cover the tires to protect them from UV rays. Check tire pressure and adjust to the manufacturer's recommended level. Disconnect the battery and store it indoors on a trickle charger, or connect the RV to shore power with a smart battery maintainer.

Interior and Plumbing Preparation

Empty and clean the refrigerator, and leave the doors propped open to prevent mold. Remove all food and anything that might attract pests. Open cabinets and drawers to allow airflow and place moisture absorbers or desiccant packs around the interior to prevent mold. Drain the fresh water tank and water heater, and flush the system with RV antifreeze if you're storing the RV in freezing temperatures. Drain the gray and black tanks completely and flush them. Leave all faucets open and pour a small amount of RV antifreeze down each drain to protect the P-traps. If you're storing in a mild climate, you might skip the antifreeze but ensure the tanks are fully drained. Close all windows and vents, and consider placing a few dryer sheets or moth balls around the interior to deter pests.

Periodic Check-Ins During Storage

Even with proper preparation, it's a good idea to check on your RV every few weeks during long-term storage. Look for signs of pest activity, water leaks, or tire issues. If the RV is connected to power, check that the battery maintainer is working and that no breakers have tripped. Run the generator for 15–20 minutes under load every month or two to keep it lubricated and prevent fuel system issues. If you notice any problems, address them promptly—small issues caught early are much easier and cheaper to fix than major damage discovered months later.

💡 Prevention Tips

  • Clean and inspect the roof before storage, and reseal any gaps or cracks.
  • Drain the plumbing system completely and add RV antifreeze if storing in freezing temperatures.
  • Disconnect the battery or use a smart maintainer to prevent it from draining or sulfating.
  • Cover the RV with a breathable cover if storing outdoors to protect it from UV and debris.
  • Check on the RV every few weeks during storage to catch any issues early.
