The 3.0L Duramax is the reason to pay attention to this truck. It gives you diesel torque, strong highway manners, and the long-range efficiency many half-ton buyers want without stepping up to a 2500HD.
The AT4 hardware adds the rugged side of the equation, while the Trailering Package, ProGrade Trailering System, Hitch View, and in-vehicle trailer app make this Sierra especially useful for boats, campers, utility trailers, and recreational equipment.
Inside, the AT4 Preferred Package adds the features that make this truck comfortable enough to drive every day, including navigation, premium audio, memory settings, heated and ventilated seating, and wireless charging.
If you're searching for a used Sierra AT4 and specifically want the 3.0 Duramax, factory trailering technology, sunroof, and premium equipment already together, this Summit White truck has the right build.
