Felt really lucky to get any money for it at all.
My main concern is making sure that 30+ft trailers aren't anymore prone to bending their frames than shorter trailers. Sounds like they aren't as long as you take care of them.
Gulp, well I guess that's good. The three stages of steel failure, you probably know, are flex (bends and returns), yield (when it remains bent) and total failure (distort and buckles). Simple solution try to keep heavier loads between axles. Overhung wt. should be minimal
Heavy loads on commercial trucks are always centered over axles.
Long M/H's, trailers and trucks do not fail when loaded properly.
Longer is better, I did mine in four steps!
