Abstract
The present invention involves pop-up camper with a roof located above a body. A lifting system is located within the body and is attached to the roof at a plurality of mounting positions. The lifting system includes a plurality of retractable posts adapted to extend in a direction along their axial centers so that when the posts are in an extended position they support the roof over the body. A mechanism adjusts the location of the mounting positions relative to the roof so that the mounting positions maintain alignment with the axial centers of the lifting system posts. The posts remained properly aligned with the mounting positions regardless of any differential thermal expansion or contraction of the roof relative the body. The adjusting mechanism centers the roof over the body by guide walls of a guide block which restrict the direction of relative movement between the posts and the mounting positions. A mounting bracket attaches the guide block to the roof and distributes forces from the posts on the roof. Each of the posts includes an end plug for sliding on the surface of the guide block. The guide block includes a channel, and each of the posts includes a rod, with the rod extending into the channel and retaining the roof relative to the posts.
