As i was reading this thread,there's one tip nobody has mentioned.
Overhere (Europe) the trailerbuilders put small spiritlevels (the one's like they use in the building trade,just the glass withe the airbubble)on the dumps.
If you put one on your dashboard and one on the trailer,it will take the guessing out off if you are level or not.
Very cheap to do and will help a lot.
like this one:

At our company though, the owner has stated that he prefers to initially dump a frameless with the trailer brakes set, pulling the tractor back toward the trailer. His theory is that by doing this you lessen the risk of laying the unit over as the trailer is stationary and not moving over any potentially uneven ground as the body is going up. Watching a few videos on YouTube, it seems that most (at least the ones that were filmed) dump this way, pulling forward carefully towards the end of the maneuver. -
That is the recommended way but the tractor must be in a straight line with the trailer or you could bend / break a draft arm and over it goes

Question!
I occasionally do haul 1 of 2 end dumps..one a regular highside for roofing tear-off, the other an endump fitted with 2 vacuum tanks that "vacuum" up rock off a roof..out of all the times I've dumped I have never released air out of the bags..
My question is what am I missing out on! Haha Or what is a good reason to do so?
BTW
My preferred method is hold the trailer handbrake and let the truck scoot back to the trailer.And don't forget your mud flaps! Some of us aren't lucky enough to have them on the swing door! -
you dump the suspension to take the bounce out of it. with the suspension aired up the dump body is resting on air bags instead of the trailer axles, and this allows it to sway more while in the air. also as the trailer is loaded the leveling valve adds air to the bags as weight is being applied to them. when it comes time to dump, while dumping the weight is shifted off the bags faster than the leveling valve can compensate. the rapid loss of weight on the bags will cause them to extend and can cause the trailer to tip over.
