Like what your building, very intense. Am starting my own camper and still gathering materials. Plywood is not cheap. Notice you build the complete frame out of 2 by 2.. I have had two campers and the weak point is the overhang above the cab. The constant vibration causes immense forces to pull down on that section wrinkling the plywood. Small cracks let water in , not good. Also noticed flat roof. Another place for water to sit. Not good. Commercial campers have a raised middle section for run off. Happy camping Tor Einar.
Thank for the comment , I'ts my first camper build. I have thougt about the overhang, I hope the plywood, strong assembly glue and cramps will hold it. The plywood is mounted to carry some of the weight on the overhang. The roof have a small curv. I will juse fiberglass and topcoat on the outside of the camper.
That will weigh around 1300 pounds. That's one problem with an overhead camper. Weight adds up real fast. My camper will be mostly bare as much as possible with only the real needed items. Portable toilet, sun shower, air mattress, small cook top, limited water tank. The lighter the load, the better the gas millage.👍
