I have access to some 4"x6"x1/4" rectangular tubing and an old crappy trailer with 2 good 7k axles and was considering building a new trailer. Does anyone have any thoughts on this as a mainframe? I know that 10" or 12" i-beam is usually used but this is free. I want to make the frame 20' (including a 3' beavertail) and would prefer a gooseneck (obviously heavily gusseted around the front). I don't know if the tubing has a high enough profile to be stiff enough. Maybe I should consult an engineer, but thought I would ask here.
