Birdie the big teardrop will be on 5' x 10' frame with a 5' high cabin. The frame is custom welded, axle and wheels from Redneck Trailer Supply.
This is my general goal and the trailer base. I'll soon post the sidewalls, which are 5'x10' 3/4" fir with sheets of 1/4" Baltic birch glued to the interior side of the walls.
