Abstract: An improvement in folding apparatus for expandable top camper bodies includes lifting and supporting apparatus for the top of the camper positioned at the front and rear of the camper body, each of which has a bi-fold panel comprised of two foldable panel sections hinged to each other and to the lateral wall of the camper and the top of the camper. The hinges are spring-loaded to self actuate and push the top upwardly to its expanded position and retain it in that position. The invention also includes resilient side stays having pre-formed crimps to induce folding for guiding the flexible fabric siding of the camper during folding to keep it away from the closure edge between the top and side panels of the camper and to keep it from wrinkling.
