Your weight distribution hitch is setup all wrong. The hitch should be setup up WITHOUT ANY AIR IN THE BAGS (as mentioned above). If you do add air to the bags after the hitch is properly setup do not add so much that it lifts the rear of the truck or else it throws the weight distribution out of whack and you could be in for a fun ride. Airbags can raise the rear end but they are nowhere near as good as a properly setup WDH. Also I've heard that the Anderson WDH does a poor job of distributing weight on heavier tongue trailers. I've always wanted to try one because they look super easy to hook up vs my Equal-izer but my Equal-izer performs flawlessly.......if it ain't broke don't fix itI'm using an Anderson No-Sway/weight distribution hitch (Hitch I'm using) and have Air Lift air helper springs (the truck does not have auto leveling) filled to ~70psi - the psi used was determined by measuring the fender height of the rear unloaded and then attaching the trailer and adding air until the squat was gone.
