Or why not pull the trailer...with a 40' diesel pusher and quit all the fooling around!Why not build 4 thin walls out of plywood, maybe insulated ,that are hinged at the bottom, and fold them up and put a ridge board across then a heavy duty tarp over it or a tent.
Then you could attach table , bed, hooks , etc......to walls for stability if you want .
No worries with wind , as long as you don't drive down the road with a fire going and the sides up .
Note: I might have a propane heater and Knight in shining armor suit for sale ,instead of a wood stove ?
