OK, you asked for it...here's some pictures of my frame, built with 2" X 2" X 1/4" angle and a tortion axle.
This is how I doubled the angle iron and made attachment points for the axle. There are actually three different locations the axle can be attached so the tongue weight could be adjusted prior to installing the fenders.
The frame is 5' wide and 8' long, but the "body" of the trailer is 9' long providing an area in the front and the back for sort of a rolled pan effect.
The body is 5' wide and only the aluminum skin extends down over the sides of the frame to hide it from view. That allowed to full height be maintained inside the body because I'm not a little guy.
