- For motorhomes, fill up the gas tank. This will prevent moisture buildup in the tank. Also make sure all your fluid levels under the hood are full.
- Drain and flush all holding tanks; fresh water, gray water, black water and hot water tanks.
- Drain all water lines, using compressed air or at least the low-point drain lines.
Note: If storing for the winter, also follow the guidelines for winterizing your RV.
- Close the LP gas tank valve(s). If your LP tanks don't already have a cover, consider purchasing at least a vinyl LP tank cover.
- Disconnect shore electric power to the RV.
- Remove all batteries from the RV and store in a place where they won't freeze. Batteries that have been frozen will never again hold a proper charge, and will more than likely have to be replaced.
- Visually check your RV for anything that might need to be repaired. Make sure you also check the roof.
- Defrost and clean the refrigerator and freezer. Place open boxes of baking soda or crumpled newspapers in the compartments to eliminate odors during storage.
- Remove all perishable items from the interior. Include in this any items that are susceptible to freezing, if storing during the winter months.
- Cover all external outlets, such as furnace outlet, to prevent critters from entering.
- Thoroughly wash the interior and the exterior of your RV. You might also consider shampooing the carpets inside and waxing the outside.
- Close all windows; leave the roof vent(s) open ever so slightly for air circulation during storage.
- Cover the tires to prevent weather-checking.
- Cover the roof air conditioner.
- Consider the purchase of a tarp to cover your RV during storage. Make sure you invest in a good tarp that can breathe.
