Miles Overview
The Sierra 3500 is GMC's heavy-duty pickup, built to tow and haul with serious capability across its trim range. It competes head-to-head with the Ford F-350 Super Duty and Ram 3500 in the heavy-duty truck segment. The Sierra 3500 drives with the commanding presence you expect from a heavy-duty truck, and the diesel provides strong low-end grunt for towing. Cabin space is generous, with available luxury trims like Denali adding upscale materials and tech features. The Pro is the work-ready choice for buyers who need Sierra 3500 capability without the extras of an SLE or Denali, so you get a vinyl floor and cloth seats instead of carpet and leather. This Pro pairs a 6.6L V8 with four-wheel drive, giving you dependable power for heavy trailer loads every day. The Pro can be ordered with the Max Trailering Package, which adds a higher-capacity radiator and integrated trailer brake controller for serious towing confidence.
