We had a 1995 Coleman that had Friction type Stabilizers, and would grab them, push them in (forward) toward the center of the camper to release and drop them down.....that is, if you are talking about the Jacks on the body of the camper, not bed supports
*Life should not be a journey to the grave with the intention of arriving safely in a pretty and well preserved body, but rather to skid in broadside, thoroughly used up, totally worn out, and loudly proclaiming - "WOW, What a ride!"
