That being said, I agree that times have shifted if you are not going to take advantage of the big power by pulling big loads and making money with said truck, I dont see the investment paying off. Especially when the gas trucks run so trouble free.
The only thing I've done to the 6.0 gassers is an occasional set of manifolds or bolts and that's cheap compared to when a smoker goes in the shop.
