The 2015 GMC Sierra Denali 2500 Diesel is a big ol' comfy truck with a long name and grille you could cook a whole hog on. We'll be evaluating it all week, so fire away with what you want to know and what you want to see me try in it. I'll do my best to oblige!
GM was officially first to launch a 2015 heavy duty pickup, and it doesn't suck. The redesigned 2015 GMC Sierra 2500 and 2015 Chevrolet Silverado 2500 are not without fault, but they offer a significantly better towing experience than what the rest of the segment can offer. For now.
