This 2026 GMC Sierra 1500 AT4 is a crew cab short box with genuine capability and refined comfort. With just 19,459 miles and one private owner, this white beauty delivers the commanding presence and performance that defines the AT4 line. The powerful 6.2L EcoTec3 V8 paired with a 10-speed automatic transmission provides authoritative power, while 4WD and an impressive array of off-road features—including off-road suspension, hill descent control, and auto-locking rear differential—make this truck equally at home on the trail or the highway. EPA-estimated 14 city / 17 highway MPG. Actual mileage may vary.
