Brian_bp,
I would definetly be interested in some pics of either the trailer or some design drawings. I skipped the bathroom as I figured I was already pushing the size and weight limits for my Landcruiser. As for the frame I was going to keep it light weight by mirrioring some design ideas from slide in truck campers as I will be taking mine appart for peices and salvage value.
As for the height of the galley upper cabinets I was going to steal an Idea from Fire Engine design and add a pull out floor so once parked you would pull the floor out from under the trailer and give yourself a 24" x 72" area to stand on while working in the kitchen.
Also where did you come up with the fiberglass shell?
