Find the drain plug on the water tank. Drain all but a few gallons. Replace the plug.

Use potable Antifreeze in the fresh water tank to prevent freezing.

Water Pump

Run the water pump until it sucks air.

Using potable Anti-freeze in the fresh water tank should prevent any problems in the lines.

Avoid Broken Pipes

Keep water in the pipes P-trap. Each month while in storage, add a little water to the kitchen and bathroom pipes.

Gray and Black Water Tanks

Keep a small amount of water in each tank. Pump a small amount of potable antifreeze into each tank.

Michelin recommends that cardboard, plastic, or plywood be placed between the tire and the storage surface.

Inflate the tires to the recommended psi on the tire.

Thoroughly clean tires with soap and water.

Store out of a high ozone area.

Cover the tires, if stored in direct sunlight.

Lower the hydraulic levelers to take some of the weight off the tires. It is important to keep the refrigerator level too if you plan to leave it stored long-term.


Leave an open container of baking soda inside to absorb odors.

Prop the door open a few inches.


Close all blinds and curtains.

Use reflective coverings inside the windows, if available.


Leave one vent cracked for air circulation. Depending on the storage environment, all other openings should be closed.

Cover the furnace vent and hot water vents with protective screens to keep out the critters.

Close any other openings inside with rags or foam that might allow critters to enter.
