What maintenance should I perform when taking my RV out of long-term storage?

Taking your RV out of long-term storage is an exciting moment, but it requires a careful, systematic approach to ensure everything is safe and functional before you hit the road. Neglecting the recommissioning process can lead to breakdowns, costly repairs, or even safety hazards. Below is a comprehensive checklist to guide you through the key maintenance steps.

1. Exterior Inspection and Systems Check

Start with a thorough walk-around of the exterior. Look for any signs of damage that may have occurred during storage, such as cracks in the fiberglass, loose seals, or damage from animals or shifting objects.

Roof and Seals: Inspect all roof seams, vent caps, and around windows and doors for cracks or gaps. Re-caulk or reseal any compromised areas to prevent water intrusion.
Tires: Check tire pressure and inspect for dry rot, cracks, or flat spots. Even if the RV sat on blocks, tires degrade over time. Inflate to the manufacturer’s recommended pressure.
Lights and Signals: Test all exterior lights, including headlights, taillights, turn signals, and brake lights. Replace any burned-out bulbs.
Awning: Extend and retract the awning, inspecting the fabric for tears and the arms for smooth operation. Clean the fabric if needed.

2. Interior Systems and Safety

Before you turn on any appliances or systems, ensure the RV is properly ventilated and that no pests have taken up residence.

Battery and Electrical System

Battery Health: Check the battery voltage. If you stored it with a trickle charger or disconnected it, reconnect it and let it charge fully. Inspect terminals for corrosion and clean them with a wire brush if necessary.
House Batteries: For deep-cycle house batteries, check the water level if they are not sealed. Top off with distilled water as needed.
Main Power: Plug the RV into shore power (if available) and test all 120V outlets and the converter/charger. Then switch to battery power and test 12V systems like lights, water pump, and furnace blower.

Plumbing and Water System

Sanitize: Before using the fresh water system, sanitize the tank and lines with a bleach solution (one-quarter cup of unscented bleach per 15 gallons of water). Let it sit for 12 hours, then flush thoroughly.
Pipes and Faucets: Run water through each fixture to clear out any air pockets and check for leaks. Turn on the water heater and check the anode rod if applicable.
Toilet and Holding Tanks: Add water to the toilet bowl and flush. Check the black tank valve and the gray tank drain for smooth operation.

Propane and Appliances

Propane System: Slowly open the propane tank valves. Test all gas appliances (stove, oven, furnace, refrigerator) for proper ignition and odor. If you smell gas, shut off the system immediately and have it professionally inspected.
Refrigerator: Start the refrigerator on electric or gas mode and verify it cools down within a few hours. Clean the exterior coils if accessible.
Furnace and Water Heater: Turn on the furnace and water heater, checking for proper operation and any unusual odors.

3. Engine and Chassis (Motorized RVs)

For Class A, B, or C motorhomes, the engine and chassis require their own recommissioning routine.

Fluids: Check engine oil, coolant, transmission fluid, and brake fluid levels. Top off as needed and look for any leaks.
Belt and Hoses: Inspect all belts for cracks or fraying and hoses for bulges or leaks. Replace if any are worn.
Fuel System: If you stored the RV with a full tank of treated fuel, start the engine and let it run. If you used stabilizer, it should still be effective. For long-term storage with untreated fuel, consider having a professional drain and replace it.
Brakes and Steering: Test the brakes, including the parking brake, and steering for smooth operation. Listen for any unusual sounds.
Generator: Start the generator and let it run under load for 30 minutes. Check the oil level and air filter.

4. Safety Equipment and Final Steps

Before you drive off, double-check your safety equipment and documentation.

Smoke and CO Detectors: Test all smoke and carbon monoxide detectors. Replace batteries if they were removed for storage.
Fire Extinguisher: Check the gauge on your fire extinguisher and ensure it is fully charged and within its expiration date.
First Aid Kit: Restock any used or expired items in your first aid kit.
Roadside Kit: Verify you have spare fuses, a basic tool kit, jumper cables, and a tire repair kit.
Wheel Lugs: Re-torque the wheel lugs to the manufacturer’s specification after the first 50 miles of driving.

This process may take a few hours, but it is well worth the effort to ensure your RV is safe, reliable, and ready for adventure. Always refer to your owner’s manual for specific maintenance intervals and procedures. If you are unsure about any step, consult a certified RV technician. Your thorough preparation is the foundation of a trouble-free season on the road.
