Been driving a 2012 Ford Raptor 6.2 the last 10 yrs 256,250 on the clock now. I bought my first GMC 1500 W/ Duramax Friday. so 13.5mpg vs 27.2 now is a huge +. Owning a truck acc. store for 18+ yrs I've seen a lot of good and bad from all makes and models. GMC is the hardest tire clearance wheel well. I plan on using ready lift 1.75''kit with UCAs and 35/1150/20 Toyo RT pro & stock wheels maybe spacers if needed to clear. would love to see pics of anyone who has this setup now Thanks MD.
