Maybe you don't but I found it to be woefully under sprung in the rear. I guess as long as you don't put much weight in the bed, the wdh will take care of the trailer.
As well, with $50-100k into a rig and camper I don't see less than $200 and an hours time as a significant waste of time or $.
Air bags mask overloaded conditions (GVWR, rear axle) which if you have your WDH adjusted per your owners manual is quite easy to do on every half ton. My prior TV was an F-150 that was overlaoded each trip. It looked and towed great with a properly adjusted WDH, providing about 1.5" rear end drop over unhitched. My opinion is that if it looks so bad to need rear suspension aids, then you are overloaded by more than a little or your WDH needs further adjustment.
For example: 8000 pounds loaded TT, 1000 pounds of TW, bed full of bikes, coolers, games, maybe some firewood, cab holding a family of 4, and 1500 pounds of payload.
