Dealer Description

Command the road and the trail in this 2020 GMC Sierra 1500 AT4, a bold and capable 4D Crew Cab built for drivers who demand strength, confidence, and refinement in equal measure. This truck comes with a Clean CARFAX showing no accidents and an odometer reading 15,440 miles below market average, making it an exceptional find. Powered by the legendary EcoTec3 6.2L V8 paired with a smooth and responsive 10-speed automatic transmission, this Sierra delivers relentless power through a proven 4WD system. Finished in Dark Sky Metallic and accented by red recovery hooks, a body-color surround grille, and spray-on bed liner with AT4 logo, its aggressive stance leaves no doubt about its off-road-ready capability. The AT4 is engineered for serious work and adventure, featuring a heavy-duty rear locking differential, hill descent control, high-capacity air filter, and a full ProGrade Trailering System with integrated trailer brake controller, hitch guidance with hitch view, in-vehicle trailering app, and HD surround vision with trailer camera provisions. LED cargo lighting, rear wheelhouse liners, and a 120-volt bed-mounted power outlet ensure this truck is ready for long days on the job site or weekends off the grid. Inside, the Jet Black leather interior with Kalahari accents delivers rugged luxury with premium comfort. Heated and ventilated front seats, heated rear outboard seats, a power sunroof, and a power sliding rear window elevate every drive. Technology is front and center with the premium GMC infotainment system featuring navigation, a multicolor 15-inch head-up display, rear camera mirror, wireless charging, 4G LTE Wi-Fi capability, and a Bose 7-speaker premium audio system. Thoughtful details like all-weather AT4 floor liners, perimeter lighting, and multiple USB and power outlets add everyday convenience. Advanced safety and driver-assist features bring confidence wherever the road leads. With its commanding presence, trail-rated capability, and refined interior, this Sierra 1500 AT4 stands ready for anything that lies ahead.
