Abstract
Abstract A collapsible trailer for camping having a wheel-mounted main body with a rigid cover forming a top for the body. The cover or top is connected to the body by foldable, collapsible end support members permitting the cover to be raised above the body portion to sufficient height to provide standing room in the trailer. The trailer contains two double-width beds each of which is movable to one side. The bunks, when not in use, are received in tracks mounted on either end of the inside of the body so that said bunks and the folding end cover support pieces can be completely contained within the trailer when the cover has been collapsed onto the body. When the cover is up and extended the beds are supported to the side and covered by canvas or other appropriate protective material to give an expanded twin double-bed camper unit. The camper body contains stabilizing legs, table means, and storage space. A door is provided in one end cover support member to permit access to the trailer when it is expanded.
