What you need is a good weight distributing system, preferably with a built in anti sway system (Reece Duel Cam or if you prefer a friction system, the Equalizer). All air bags can do is prop up the rear of your truck and the WD system will actually LIFT the rear while transferring the weight to where it's needed. It will replace lost weight on the front axles while reducing the increase on the rear. Just be sure you SIZE and ADJUST the WD system correctly. Usually the spring bar size is determined by using 15% of the trailers GVWR. Get as close to that number as possible without being UNDER it.
Good luck / Skip
