I want a warranty. You can't have that if you delete the Dpf and urea systems. The only reason I'm getting one is for work. I want something that can go straight to the dealer if something goes wrong and they have no excuse to hassle me. The crew cab has been awesome, but the constant worry of something going wrong is always there. I'm looking at Fords because I know nothing about them and they are cheaper than duramaxs and have the best interior IMHO. I sit in the truck for 12 hours a day. I want something nicer to sit in than this LT Chevy interior. If I find an LT dmax for the right price, I'll get it... But 75% sure I won't mod it at all, unless it comes from this one specific dealer who is cool about it.
