Remove all trash, food and perishable items from the camper and thoroughly clean all surfaces, including the inside of the refrigerator. Leaving perishable items in the camper allows germs to spread and mold to grow.
Completely drain all water systems in the camper, including the water heater. If water is left in any of the pipes, the cold temperature in the winter months will cause the water to freeze and expand and often cause the pipes to burst. Once drained, make sure all water valves are closed.
Turn off the propane cylinder valve and disconnect the 12-volt tongue-mounted battery on the trailer. If the trailer is being stored inside an enclosed building, remove the propane cylinder and battery and store them in a well-ventilated location. Keep the battery charged.
Cover all exterior appliance vents to keep insects and small animals out. Use plastic wrap to seal the vents.
Inspect and repair seams in the roof and body canvas and check seals on any roof-mounted accessories. Also, open roof accessories once every two months to check seals. By making repairs now, you lessen the work necessary to get you back on the road in the spring.
Lubricate all moving parts, including the pop-up lift system, hinges and hitches. This prevents rust and ensures smooth operation when you choose to expand your trailer again.
Secure all doors and hatches so they are water tight. Moisture can enter small cracks and cause damage to the trailer.
Park the pop-up camper at a slight downward angle with the tongue end down. This prevents snow, ice and water from gathering on the top. If large amounts of snow gather on the camper during winter months, remove the snow to prevent damage from continued exposure to the weight.
