Questions about new TT upgrade from Tent Camper

Besides winterizing, consider the surface the trailer will be parked on. You may want to place wood under the tires, if you're parking on grass / dirt. Consider purchasing some tire covers and do a thorough springtime inspection.

Outdoor storage will weather the tires and caulking faster than being indoors. In the spring, check caulking on roof seams, around running lights, doors, and windows. Clean and recaulk any cracks.
