FWC has long advised not using camper off the truck. The wood tub is stapled to the aluminum frame. The bottom of the camper would need to be fully supported, saw horses that could carry the weight, with a sheet of plywood, 3/4" plywood X's and a full sheet, dolly, or trailer. Think of the camper fully load and having the tub break away in the back country. "High risk low reward" Jacks won't lower camper all the way, maybe 1' from surface
