It is a one-owner vehicle with a clean AutoCheck vehicle history report, reinforcing its quality and care.

Powertrain and Capability
At the core is the Duramax diesel, known for its durability, torque delivery, and long-term dependability. Matched with the Allison transmission, this truck offers confident towing, smooth shifting, and excellent control under load. Features such as the Heavy-Duty Handling/Trailering Suspension, exhaust brake, electronic shift transfer case, and Hill Descent Control make this Sierra exceptionally capable for hauling, towing, and challenging terrain.

Denali Trim – Premium Interior and Comfort
The Denali cabin sets the benchmark for luxury in the heavy-duty segment. The interior is finished in Jet Black perforated leather, with heated and ventilated front bucket seats, a heated leather-wrapped steering wheel, and dual-zone automatic climate control. Power-adjustable pedals, memory seating, and a power sunroof further enhance comfort and customization for the driver.

The 8-inch multi-color driver information display keeps vital vehicle data easily accessible, while GMC 4G LTE connectivity and OnStar capability add modern convenience and peace of mind.

Trailering and Work-Focused Equipment
Designed for serious towing, this truck includes the Duramax Plus Package, Gooseneck/5th Wheel Prep Package, trailering equipment, rear wheelhouse liners, and rear bumper corner steps. Ultrasonic front and rear park assist, backup camera, and hitch guidance features improve visibility and confidence when maneuvering with a trailer attached.

Safety and Driver Assistance
Advanced safety features include Forward Collision Alert, Lane Departure Warning, Driver Alert Package, and a comprehensive airbag system. These technologies are designed to enhance awareness and support the driver during long hauls or daily use.

Exterior Presence
