Air bags
I picked up the FW today and measured the drop on the rear and it went down 3" not the 1 1/2" I guessed before at what point do you considerer air bags?

If you have the camper package with the upper overload springs, you just need the Torklift upper StableLoads to engage that spring sooner. If you do not, I would suggest Timbrens or SuperSprings to get greater spring rate. Bags will help some of that sag, but 3" worth of sag will be hard on the bags and most likely make your truck mushy and porpoising.
