Abstract
Abstract A collapsible camping trailer or camper having a horizontal top panel which serves as the ceiling of the camper in the opened position and as a flat storage bed when the camper is in the collapsed position. A rigid front panel is pivotally affixed at its upper end to one edge of the top panel and has tracking members at its lower end received by a pair of channels in the camper floor. The rigid front panel collapses from a vertical position when the trailer is opened to a horizontal collapsed position between the camper floor and the top panel which also collapses, when in the closed storage position. There are corner supports affixed to another edge of the top panel which also pivot between opened and closed positions to add structural stability to the camper when in the opened position. The top panel also can be provided with guide ways which can be used as a storage bed for two-wheeled vehicles when the camper is in the collapsed storage position.
