This is a light, custom built, hard wall pop up Camper. The walls, floor and roof are insulated with 1.5" styrofoam. The empty weight is 860kg. The process of lifting the walls is done with a 12v electric linear actuator. The outside dimensions are 8' x 14' with a 6' front bed. It is mounted on the truck with a "torsion free" flatbed. It is on a ford f150. The flatbed can easily be modified for other makes of truck. I am selling it because of health reasons.
