okay - here is some more info. The guy that made it made several, so likely it is molded, then decided to stop making them, is just trying to sell for what he put into them.. Weighs 400#, costs $1200, has a roof vent and tiny shelf inside, a custom cut mattress for it is an extra $100. If someone is interested the place to contact is Mobuilt RV Repair, 360-457-4101, they are just letting him put one there to try to sell it for him. They do not know the exact measurements but I guess if there was interest they could go measure it.
The ultimate light-weight!
PS - Ron, you probably know more than I do, but I believe fiberglass can be layer up on a frame, or temporary mold (like working with paper mache) folks around here build one of a kind small boats, but obviously this little trailer looks too rounded for that method.
