When I first bought my camper, I had the dealer finish setting up my Ram 2500. That included airbags. The ride was really bad with lots of sway. I cranked up the Rancho shocks to help. The ride became stiff and harsh and the sway was still an issue. I tinkered and found dropping from roughly 45 psi to about 15 psi helped a lot.
A year or so later one of the airbags tore. I hardly noticed the difference since I had dropped back to about 10 psi. Later I got rid of the airbags and went with Supersprings. Wow, what a difference. I was able to lower the shock settings and had a great ride with minimal sway. No more airbags for me!
On my new Ram 3500 truck I still needed a bit of help mostly to keep the headlights from pointing too high. Timbrens solved the issue. I could still aid Supersprings but I seem to be doing well without.
