Alright guys looking for some advice. I have a 6 x 12 enclosed trailer that I bought years ago. Single axle if I had to guess 3500# axle. The frame has rotted out from under it. Frame is 2 x 3 rectangular tubing. My guess is 1/8" wall. The center sections being press broke 1/8" z bends. My question is 1/8" wall tubing sufficient for this trailer? And then what do u think about 2x2 1/8" angle iron the the cross bars with two runs running front to back to eliminate some of the twist in the angle? I wanna build a good trailer frame but want to keep cost reasonable. I don't wanna spend money overbuilding. B/c as said in other threads is only costing me payload.
