2015 gmc sierra & chevys

[Nitramiii]

I'm not saying Gmc is the best truck on the planet, but hear is what I do know. I bought the 2014 5.2 for my son and a 6.2 6months later for myself. I came out of a 2008 6.2. My sons truck seemed to pull and sound much quiter than my old 6.2. We stomped it side by side at 40 mph and he hammered my old 6.2. My new 6.2 now takes him at any given speed when we tested them recently. As for towing a 24 champion, the 6.2 does very well when compared to my 2008 6.2. It's quiter, does not hunt for gears and the tow haul is usable without being so mechanically rough. It's a compleTly different truck than the old body style. In town (Lafayette) around 13-14. Highway 17-18 @ 75-80mph. Towing short trip to c point 11 mph.
