Air bags work well and I have used them for years with my truck camper. However after a couple of years of using just the bags, I had some custom overloads built (which carry more weight and make contact sooner) and they made a lot more of a difference especially in sway than the bags do. With the bags only, I get more sway side to side. Nowadays, I drop the camper on the truck, put very minimal air in the bags to help pick up the rear, but i make sure the overloads are still engaged. With this setup it drives great! I'm actually getting ready to try something else to see if I can get it even better. I know my setup is overkill and I could put more weight on the truck than it can hold, but thats not what I'm trying to do. I'm more about getting it to drive and ride better and safer. I also haul a 20ft Enclosed trailer with the same setup on the freeway no problem.
Let me know if you have any questions and I'll try and answer them, as I have tried many different ways of doing this.
Oh yeah, I almost forgot, Look in the "My Photos" tab below my avatar picture and you can see my custom overload springs
