I tried airbags and immediately had an issue with bounce and sway. I lowered the pressure to the point where the bags hardly helped leveling the rig but at least the bounce and sway were decreased.
I had Rancho shocks and to help with the bounce and sway I had the rear shocks set on high. The ride was poor with lots of jolts when driving over highway tar strips, etc. It took a couple of years before I finally got rid of the airbags, added Supersprings and was then able to dial back on the shocks. The Supersprings made all the difference! I will never mess with airbags again.
