  • The odometer on this GMC indicates roughly 12,000 miles.
  • The attached Carfax history report lists no accidents or mileage discrepancies in this GMC's past. It also shows 1 owner from new.
  • A build sheet is provided in the photo gallery showing that this GMC carried an MSRP of $64,010 when new. A partial list of notable equipment includes the AT4 Package, a bed-mounted power outlet, power-adjustable heated and ventilated front seats, heated rear seats, an integrated trailer brake controller, and more as detailed below.
  • Modifications reported by the seller are extensive, and some notable modifications include 17-inch Raceline wheels, a ReadyLIFT 1.75-inch leveling kit, a RIGd UltraSwing hitch system, an OVS Nomadic Awning 270-degree, Yakima 10-gallon RoadShower, and much more listed below.
  • GMC launched the current-generation Sierra for 2019. The truck was again related to the Chevrolet Silverado under the sheet metal but designers went to great lengths to differentiate the two models; they notably gave the front end a new look. GMC also offered some features that were not available to Chevrolet buyers at launch, like the clever MultiPro tailgate. Sierra production continues in 2022. The AT4 trim level denotes a 2-inch lift kit from the factory, as well as other off-road specific features.
  • Power comes from a 3.0-liter turbodiesel inline-6 engine, rated at 277 horsepower and 460 lb-ft of torque. It spins the rear or all four wheels via a 10-speed automatic transmission.
