Hey all, I’m hoping to buy a 2011 3500 with the G56 and 4x4. Crew cab long bed dually. It currently has 90k miles on it, it’s been deleted but I’m not exactly sure on what all has been done to it. Keep in mind that I’ll be coming from an 01 7.3, and the only experience I have with Cummins is an 06 2500. What kind of fuel mileage will I be looking at with this pickup? Also, what are some good mods I can do for performance/reliability for it? It will be my welding rig so it’ll be a daily and I need it to last as long as possible. Is 2011 a good year for the 6.7?
