Abstract: A tent camper for mounting over the cargo compartment of a pickup trust is disclosed. The tent camper includes a collapsible frame and a cloth top stretched over the frame. The frame includes inverted U-shaped fore and aft supports pivotally mounted to the sidewalls of the cargo compartment of the pickup. The cloth top, having a generally rectangular top and four depending sides, is sized to extend over the floor of the cargo compartment and the lowered tailgate. The lower edges of the depending sides are attached to the outside edges of the sidewalls and the lowered tailgate by snaps. The fore and aft supports are pulled foward and rearward by straps so that the fore and aft supports are forced away from one another thus keeping the fabric taut and properly positioned over the pickup truck.

Abstract: A large bore, long stroke, low friction, hydraulic actuator having dual hydrostatic bearings permitting elastic deformation of the piston rod while inhibiting metal to metal contact between either the piston head or the deformed piston rod and the walls of the hydraulic cylinder. The actuator employs a safe and highly reliable metering orifice cushion decelerating means. Piston displacement is constantly monitored by a completely internal, magnetostrictive, sonic delay line displacement measuring means.
