ABSTRACT:
A camper lifter device for lifting and transporting campers comprising an adjustable frame having first and second side members with a lifting assembly adjustably carried on each side frame member. A lifting cable is attached via pulleys to two angle iron lifters slidably carried on each lifting structure dimensioned for fitting underneath each side of a camper to be lifted or lowered with the cables being wrapped around a cable drum mounted on a front structural member of the frame for effectively shortening and lengthening the cable and lifting and lowering the two lifters slidably coupled to the lifting mechanism. First and second structural members are removably attached to the first and second side members for carrying the camper during periods when the camper is not in use but it is desired to leave the camper on the lifter device, i.e.; once the camper is removed from a truck bed it can be lowered onto the first and second structural members thereby with its weight resting on the frame itself and not on the lifters. This insures stability and portability during storage periods.
