Shocks don't support weight, they dampen motion. Air bags are useful for leveling the rear of the truck if the pin weight of the 5th wheel causes it to squat excessively as well as increasing overall rear spring rate. Neither will change the truck's GVWR, payload, GAWR or GCWR ratings.

Pretty Much X2.
Shocks control bounce after hitting a bump, or bridge transition. Air Bags, help level excessive squat. Only the OP can decide if he wants to run over the TV listed GVWR.
The big question is how does it feel while towing.
