when we bought our current 5er we had a 2011 F250, it had the fx4, snow plow prep etc, I put in air bags and it rode BAD. this truck was a long bed, I dropped the bags to 10psi empty and it was better. However I found I was running the bags at 60psi loaded to level it out and I had a lot of chucking. ANd yes the 2011 up f250 and 350SRW share almost all the exact running gear.
fast fwd, my current DRW has no bags and rides bad empty, rides decent when loaded and has no bags. I still get some chucking but im certain that my cheap reese hitch isn't helping it.
Im not saying go buy a Dually I am saying your air bags are a band aid that might be contributing to this issue.
