Airbags were a disaster on my truck camper. Set low they did little or nothing. Anything over about 25 psi helped level the camper but the sway was awful. I tried to help the situation with Rancho shocks set on high. That was also a mistake and gave me a really poor ride. My wife complained that even small bumps or highway tar strips hurt her neck.
I ditched the airbags and put on Supersprings. That gave the truck the spring capacity it needed for a 4000# plus load. I was able to soften the shocks to about 5 front and 7 rear. Both the sway and the jolting ride were fixed. On my current truck I am using Timbrens and they work quite well. I suspect I would still have even a better drive if I install Supersprings.
