Looking for input on side dump trailers.

I am thinking of purchasing a side dump trailer.
Really would like an do appreciate your input and suggestions.

I have noticed another contractors highway tractor a Ford LTL9000 that pulls a side dump and its frame cross braces are all bent,
from the back of cab to the axles -
I assume from the twisting of the truck frame when the side dump tilts to dump, what do you think?

Any experience with side dump trailers? Which would you stay away from and the reasons?

Which make do you like and the reasons why?

Is there a manuf. whose side dump does not once it raisers the box to that point where its over center and
it DOES NOT quickly tilt over but rather slowing finishes tilting over?

Thinking air ride suspension, any comments?

Three axles with last axle a lift, any comments?

Also will look at used side dumps, any comments on what to look out for in the used market?

They are expensive new, I have a quote for a nicely equipped side dump at $81,000.00 all taxes FET & State sales tax.

With what ever you reply it be greatly appreciated.
Thank you.
