  2025 GMC Sierra 2500 At4x
The best:Overall beast. Tows good, rides good, and it’s overall very quiet.
The worst:First probably like everyone else the emissions system. Secondly the audio system. Clips out with no fix in site and unless you add a sub, the audio is just outright weak.

  2015 GMC Sierra 2500 Denali HD 6.0
The best:ONLY the look or appearance of the vehicle.
The worst:Multiple issues. Installed third transmission and transfer case at 96k. Radiator at 128k. New engine at 129k. GM unwilling to reimburse or compensate for any of the costs. Costs to me out of pocket for repairs almost USD $20,000.00 after five year warranty expired. Been GM consumer for years. Never again.
