It sure is unusual. It has a lot of
Bigfoot similarities, but it looks like it is made of at least 5 molded pieces. The top, front, back and both sides appear to be molded separately. It's too new to be a prototype of the original 80's Goucho units and
Bigfoot did not sell any of the "Milenium" (made from
fiberglass flat panels) units until 2000, or maybe 1999. Possibly a prototype for the Milenium or some other experimental trailers.
