Air bags/air suspension at best complicate WDH adjustment. I can't think of any reason why a half ton or smaller SUV would need it.

My experience with the full sized 08 Durango has been soft suspension and horrible OEM shocks.

I upgraded the shocks which helped dramatically. Adding air bags just helps stiffen the rear end for when I pull but are not necessary for everyday driving. It doesn't affect my WDH and I don't use the bags to "extend" my payload or axle capacities as I'm within my weight MAXs.
