This vehicle arrives as a recent trade-in with one previous owner and a clean vehicle history. The low mileage of 5,486 miles confirms this is essentially a new truck with minimal real-world use. You're purchasing a vehicle that has been gently operated and maintained with care.

This truck is certified and carries the remainder of the factory warranty, providing you with confidence and protection. GMC's comprehensive coverage means you can focus on the work ahead rather than unexpected expenses. The certification process ensures all systems have been thoroughly inspected and meet manufacturer standards.

The AT4 trim level combines rugged capability with refined comfort. The Max Trailering Package delivers the frame reinforcement, suspension upgrades, and towing infrastructure for serious hauling. The Snow Plow Prep package adds the electrical capacity and protective skid plating for professional or demanding applications. Whether you're managing a work fleet or tackling personal projects, this Sierra is engineered to handle the task.

The technology suite keeps you connected and informed. The 15-inch head-up display projects critical information directly into your line of sight. The in-vehicle trailering system app and hitch guidance with hitch view simplify complex maneuvering. Wireless charging and multiple USB ports ensure your devices stay powered throughout the day.

The interior balances durability with comfort through leather-appointed seating, heated and cooled front seats, and a heated steering wheel for winter conditions. Premium floor liners protect the cabin investment. The power sunroof adds light and openness to the driving environment.

This 2026 Sierra 2500HD AT4 represents the full-size diesel truck experience without compromise. We invite you to examine this truck in our showroom and take it on a test drive to confirm the quality and capability it delivers.
