2500 air suspension question; How much weight can it level?

[jeffjcalweb]

This is just out of curiosity. Anyone know - as in documented/measured - how much payload the 2500 air suspension is capable of handling before it gives up? Anyone aware of it not being able to level a typical 2500 payload rating, for example around 2,200 lbs?

Works fine for a pallet of St Aug in the bed and a trailer full of dirt. Since it was dry, that's probably 2-2.5k in the bed and 500lb tongue weight
