Abstract
Abstract A tripod camper jack has two legs fixed to a post support and a third leg hinged to the support for movement between an operative position extending away from the fixed legs and a folded position folded back along a first one of the fixed legs. The second one of the fixed legs carries a roller and the third leg carries a second roller. When the third leg is in its folded position, the rollers are aligned and the jack may be tilted to raise feet of the fixed legs and rolled on the rollers. In an alternate embodiment, a saddle is secured to a slide on the post in either an operative position extending crosswise of the post or a storage position extending lengthwise of the post.
