Miles Overview
The 2021 Sierra 1500 is GMC's full-size pickup, offered in work-oriented and luxury trims that range from the Elevation to the Denali. It lines up against the Ford F-150, Ram 1500, and Chevrolet Silverado 1500, with the Denali aiming at the luxury end of the segment. The Sierra drives with a composed, planted feel, and the steering is precise for a truck of this size. The cabin is roomy and well built, and the available MultiPro tailgate adds useful versatility for loading and reaching the bed. The AT4 is GMC's off-road-oriented Sierra, sitting above the Elevation and SLT but below the luxury Denali, trading some chrome for skid plates and a factory lift. The 2-inch factory lift, monotube shocks, and auto-locking rear diff make this the Sierra to pick if you actually plan to leave the pavement.
