ABSTRACT:
A cableless power lift assembly for raising and lowering the roof structure or camper top of a pop-up camper includes an elongated drive housing mounted to the base of a pop-up camper and a pair of aligned left and right threaded screw drives mounted in the drive housing for rotatable movement therein. A motor is attached to the left and right screw drives for rotatably driving the screw drives to raise the camper top upon actuation of said motor in a first direction and lower the camper top upon actuation of the motor in an opposite second direction. In addition, collapsible lifting apparatus is also provided for moving the camper top between a generally horizontal lowered or collapsed position and a generally horizontal raised or extended position. In a preferred embodiment, an air conditioning unit is mounted in the camper top.
