The 2023 GMC Sierra 1500 AT4 in Summit White with Jet Black interior and Kalahari accents delivers premium truck comfort, refined 4WD capability, and smooth diesel-style torque in a package built for drivers who want more than just a plain work truck. Powered by a 3.0L I6 engine and paired with a 10-speed automatic transmission, this Sierra AT4 offers confident towing and hauling ability, composed highway manners, and the kind of upscale off-road-ready presence that makes it feel equally at home on the ranch, the road, or the jobsite. With 79,985 miles, this Crew Cab still brings strong value, broad buyer appeal, and premium truck utility in a package that knows how to work without looking stripped down.
