Abstract: A trailer hitch is provided for releasable attachment to a trailer frame. At least one aperture is defined in the trailer frame. The trailer hitch includes an elongated cross member having a first end and a second end, a first side member extending from the first end of the elongated cross member to a coupler and a second side member extending from the second end of the elongated cross member to the coupler. At least one aperture is defined in the trailer hitch in a position of coaxial alignment with the aperture defined in the frame when the trailer hitch is in a towing position A removable lock pin is adapted to extend through the apertures in the frame and the trailer hitch to secure the cross member in a fixed position relative to the frame.

Abstract: A self-contained convertible recreational vehicle or travel trailer including an open-top box type body section provided with rigid forward and aft cover sections which are movable between collapsed and extended positions with respect to the body section and which provide a roof for the body section both when the cover sections are collapsed for towing of the trailer and when they are extended to open the trailer for camping. Torsion bar means assist in moving the forward and aft cover sections between their collapsed and extended positions. In one embodiment, spring biased sliding beds mounted at opposite ends of the body portion adjacent the top of the end walls thereof, extend to an outward position in engaging relationship with the lower margins of the opposed end walls of each of the forward and aft sections to assist in moving the cover sections between their collapsed and extended positions.
