nuCamp suggest that storing your unit under a roof or cover when your unit is not in use for an extended amount of time is always a good idea. When the time comes to store your unit outdoors if not within a building you also have the option of using a temporary cover to drape over your unit. The drape over style will protect the surfaces and finish from UV breakdown, dirt, leaves, birds and other airborne contaminates. Our opinion is to have the unit covered rather than exposed to the outdoor elements.
