Next suspension mod

I have no overloads on my '96 Dodge, but do have airbags and rear anti-sway bar. My TC is 4200 pounds. I have been running this setup since 2004, with no problems from the airbags. I did add a leaf to each spring pack in about 2008. That was a mistake. No problem with the TC loaded, and could run less psi in the bags. But they really did nothing the bags did not do. Empty, the added springs made my truck ride like a ping pong ball. I got used to it, but fact is I wasted money and created a stiffer ride with adding springs.
