I purposely chose not to get the factory auto-level, and don't think you can go wrong with that truck.
My previous truck had the Kelderman 4-link. The factory auto-level doesn't compare to that system so I wasn't interested. Most aftermarket suspension components say that they are not compatible with the factory air ride. I didn't want to limit myself to the factory options, and if for some reason I want air in the future, I'll go back to Kelderman for their more robust 4-link system. I've been pleasantly surprised with the progressive leafs so far.
