Said formula is ok, but from my experience, it falls way short of what is real. IIRC overhang/wheelbase times hitch weight equals amount removed.
Issue with formula, is it does not take into account the frame from being initially rail high, to later depending on load, to tail low. Reality, is the amount removed initially is less, way less in some cases, than formula. Then it gets closer as more hitch weight is added, eventually, the formula is guessing too low, as you get closer to bottoming out the suspension.
It also does not take into account the rear spring rating, or stiffness. I switched from 6400 lb springs, to 8400 lb springs on my 96 crew cab, went from pulling a bit over 400 lbs off FA, to 300 lbs, with 1500 lbs of hitch weight.
My experience with said formula is t bcc at it gives you an idea, but reality, it is probably not correct enough for many of us!
