Hi Toy Runner,
What is a 1x1 camper? I've drawn up some plans myself, but would like to see your's. I don't have many exact figures for costs being I'm here in Peru, but my rough guess/estimate comes up to $3400 for a 7 1/2 x 9 foot camper, with a 4 foot motorcycle garage in front of it. That is using a 1x2 frame, with 2x4s on all corners, plywood covering inside and out, insulated, bench/bunk beds, table, sink, 2 burner stove, closet and overhead storage, door and 1 window, and a porta-a-potty. I'm going to try to attach a pdf file with my notes and drawings.
