RV Tips - Long-Term Storage

Preparing your recreational vehicle (RV) for long-term storage is crucial for maintaining its condition and preventing costly damage. This guide provides essential steps to ensure your RV is ready for its hibernation.

I. Exterior and Structure PreparationA. Cleaning and Maintenance

Before storage, a thorough cleaning of the exterior is essential to protect the finish.

• Wash and wax the exterior to protect the paint from environmental damage.
• Clean out all slide-outs, awnings, and seals, applying UV protectant or a seal conditioner to prevent drying and cracking.
• Check the roof for any cracks or leaks, and make necessary repairs.
• Inflate tires to the maximum recommended PSI to prevent flat spots during storage. Consider placing the RV on blocks to take weight off the tires, especially for very long-term storage.
• Cover all exterior vents to keep pests out.
• Ensure all windows and vents are completely sealed and closed.

B. Securing the RV

Choose a suitable location for storage, such as a covered facility or a secured, level outdoor space in a location.

Item	Action	Notes
RV Cover	Use a breathable, properly sized RV cover	Avoid using standard tarps, which can trap moisture.
Wheel Chocks	Securely place chocks on all wheels	This prevents any accidental movement.
Jacks/Levelers	Retract all jacks and levelers	Store the RV in a level position if possible.
Security	Install a hitch lock and ensure all doors/compartments are locked	Consider adding an alarm or tracking device.

II. Interior Preparation

Pest control and moisture management are the primary concerns for the interior.

A. Pest Prevention

• Remove all food items, including canned goods, dry goods, and anything in the refrigerator/freezer.
• Clean all surfaces, cabinets, and appliances to eliminate crumbs and odors.
• Place mothballs or other pest repellents in potential entry points and cabinets, but avoid areas where they could damage upholstery or electronics.
• Stuff steel wool into any small exterior openings, such as around pipes or cables, to deter rodents.

B. Moisture Control

Excess moisture can lead to mildew and mold growth.

• Open all cabinets and drawers slightly to allow for air circulation.
• Place dehumidifiers or moisture-absorbing products (e.g., desiccant packs) throughout the RV, especially in the bathroom and kitchen.
• Ensure the RV is stored with enough ventilation.

III. Systems and Utility ManagementA. Water System

This is a critical step to prevent freeze damage.

• Drain all fresh, gray, and black water tanks completely. Flush the black tank until the water runs clear.
• Bypass the water heater (if applicable) and drain it as well.
• Pump RV antifreeze through all water lines, toilets, and fixtures, including the shower and sink.
• Leave all sink and shower faucets open after adding antifreeze.
• If your RV has a washing machine or dishwasher, consult the owner's manual for specific winterizing instructions.

B. Battery and Power

Batteries lose charge over time, and a dead battery can be permanently damaged.

• Disconnect the RV's chassis and house batteries.
• If possible, remove the batteries and store them in a cool, dry place.
• Use a trickle charger or maintainer to keep the batteries charged periodically, or consider charging them once a month.
• Turn off the main power breaker.

C. Engine and Fuel

Proper engine and fuel preparation will ensure a smooth start when you take it out of storage in the spring.

• Top off the fuel tank and add a fuel stabilizer according to the product's instructions. Run the engine for a short time to circulate the stabilized fuel through the entire system.
• Change the oil and oil filter before storage. Used oil contains contaminants that can damage internal engine parts over time.
• If storing outdoors, consider placing a cover over the exhaust pipe to deter pests, but remember to remove it before starting the engine.
