Overtight weight distribution brackets bent frame....

It seems that there is a lot more going on there than over tight saddle brackets. I see where the saddle bolt was tightened down too tight but the top of the frame looks distorted as well. I'm seeing alot of rust. I assume that is a box frame? considering the age of the trailer, I would be concerned that the frame is rusting from the inside and the metal is weakened.

I would have the entire A frame replaced by a professional welder. Not as expensive as you might think.

Any idea what your tongue weight is?
