I would not do front leveling. The reason the truck sits high in the rear is for weight hauling. Leveling it out unloaded will create problems when loaded and the truck will not behave correctly if not also cause issue in the geometry change. When I load my dually to max, its as level as it can get and handles very nicely

Yeah killer deal, even the wife was not able to pass this one The dealer was hurting and cost of diesel at $4.95 worked all in our favor
