As some of you know on teardroptimes I came up with a question of makeing a wood frame. and got many interesting answers and some links and photo's.
In so looking today I found that a trailer company called Teton makes one a fithwheel, I beleave.
I also found this very interesting site with interesting answers as to using exsiting trailer frames and homemade ones.
His subject is way to big for the trailers for this site but the idea seems sound.
