I thought I'd post a thread to help in my planning for my build that will start this fall. The plan is for a 5'x8' (profile undecided). I'm building the trailer. It won't be my first, I built a car hauler years ago during my stock car racing days. I'm planning on using one of the axles (3500 lb.) and one set of leafs. I plan to make it out of 2"x2"X.125 square" tubing with either square cross braces or 2"x2" angle. I'm not sure of the tongue bar. Is 2"x2" sufficient of maybe 2"x3"?
I will have more (many more) questions and plan on using this thread until the build starts. I can't wait.
