Being on the road is one of the great pleasures of owning a motorhome. However, at one point or another, you’re going to have to put that rig in storage. If you want to keep your motorhome safe during the off-season, here is a storage checklist to help keep your motor home in great condition.
Fill the motorhome fuel tank to reduce excessive moisture buildup.
Check coolant level and add antifreeze if necessary. Use an appropriate coolant/water ratio that will protect to the lowest temperature expected during the storage period.
Change the engine oil to the recommended viscosity to aid with cold weather starting.
Park the motorhome as level as possible.
Ensure the battery has a full charge, then disconnect both the chassis and coach batteries using the battery disconnect switch. Charge the batteries monthly with a trickle charger or smart charger.
Wash the motorhome. If exposed to road salts, thoroughly wash and flush the exterior and undercarriage.
Remove all perishable items and anything that can freeze (canned goods, medicine, etc). Leave the refrigerator door ajar. Ensure all controls are turned off.
Ventilate the living area by opening drawers, cabinets, closets, etc.
Drain the grey and black water holding tanks, toilet and living area water system. Deodorize and allow to dry. Turn off the water heater. Drain the fresh water tank and water heater. Refer to the Cold Temperature Storage section in this manual for winterizing procedures.
Turn off the LP Gas tank valve switch
