I've been on this site about 3 years ago - I was working out a custom design I called the Mobile Surf Shack, it was a bit of a hybrid between the Widget design and the old Popular Science "Weekend Trailer" from April 1946. The idea was to build a large teardrop style trailer (small travel trailer) big enough for a closet washroom with a chemical toilet. I was thinking of using a Tupperware storage box as a bath tub ( I've used this before when my plumbing backed up - works rather well). I was planing on having roller racks placed on the back of the long sloping back of the trailer to strap canoes and surfboards to. I made a google sketchup model of my idea but I've been having trouble resizing it.
Bye for now.
