I did poorly when it came to math... I now regret not trying harder
I need to make a special purpose 25 foot trailer which can not appear
Typically a 15,000 pound capacity trailer would have 6" C Channel
(frame) with 6" Junior I Beams (cross members) spaced 18" apart.
I am proposing that we use 4" square tubing for the entire frame
structure with cross beams spaced at 12"
Is this frame as strong as "typical" or stronger.
An additional thought: several manufacturers do what they call fold
back trailer tongues... essentially they double the beam from directly
in fron of the tires to the tongue...
