it sounds like you must have over load springs, that work as the truck body drops the springs come into contact with the overload spring perches on the frame.
Your not loaded enough to make them come into play full time so they BANG every time the springs hit them
As you crank up the air bags they you are raising the back so they never hit again.
This.
Ditch the airbags and add lower Stableloads . You’ll be all set.
I'm not convinced that this is true with a 4000 pound camper. The lower pressures he was experimenting with should have allowed the weight to compress the suspension enough to get full engagement out of the various parts of his OEM suspension.
I was having issues and called airlift who makes my bags and tech support recommended running up to 95 psi. I find I like the ride around 75 psi so consider trying out higher pressures. Air it up and see how high you can go before those extensions you talk about lose contact and you may find that you can go higher pressure and still be comfortable with the suspension.
In addition to raising the vehicle as the pressure increases, the "firmness" also increases. It's a dance between the vehicle springs and the airbags and the goal is to find the sweet spot where they work together the way you want.
