Ebony Twilight Metallic gives this 2023 GMC Sierra 2500HD AT4 a deep, upscale finish, but this truck is built around serious hardware. With
53,493 miles, four-wheel drive, a 6.6-liter Duramax turbodiesel V8 and Allison 10-speed automatic transmission, it combines heavy-duty capability with the off-road-oriented AT4 package and a leather-trimmed Crew Cab cabin. For a buyer who needs a truck that can work during the week and still feel premium on the weekend, this Sierra HD has the right foundation.

The Duramax 6.6-liter turbodiesel V8 was rated at 445 horsepower and
910 lb.-ft. of torque for 2023, and it is paired with the Allison 10-speed automatic. That combination is designed for the kind of low-rpm pulling strength heavy-duty truck owners value when towing, hauling or moving a loaded truck through highway traffic. Four-wheel drive broadens the Sierra’s capability beyond pavement, while the HD chassis, substantial braking system and truck-specific cooling and driveline components are engineered for workloads well beyond what a light-duty pickup is intended to handle.

AT4 trim adds a more purposeful off-road and premium character. The package is known for its off-road suspension tuning, Rancho shocks, skid-plate protection and distinctive exterior treatment. The Crew Cab configuration gives rear passengers genuine usable space, making the truck workable for a crew, family or longer-distance travel. Leather seating, a heated steering wheel and heated and ventilated front seating bring comfort into a vehicle whose mechanical mission is otherwise very serious.

Inside, GMC designed the Sierra HD around clear controls and truck-specific information. The center stack places trailering, drivetrain and climate functions within easy reach, while the driver gets a commanding seating position and broad outward visibility.
Rear-seat space can handle adults comfortably, and the cab provides useful storage for work gear, electronics and personal items. The pickup bed adds the hauling flexibility that remains the reason to own a heavy-duty truck in the first place.

The AT4 appearance works especially well with Ebony Twilight Metallic.
Dark exterior accents, the AT4 grille treatment, aggressive wheel-and-tire proportions and elevated stance give the truck a purposeful look without going into aftermarket territory. That factory-engineered approach matters for buyers who want off-road style and capability while retaining the cohesion of an original manufacturer package.

Heavy-duty trucks are often judged by what they can do when loaded, and this Sierra’s Duramax-and-Allison combination is the core of that story. Whether the job involves equipment, a large trailer, recreational toys or simply the need for substantial reserve capability, the 2500HD platform provides a much broader operating envelope than a half-ton. Four-wheel drive also makes the truck better suited to job sites, boat ramps, unpaved areas and the severe rain that can hit roads around Tampa Bay.

This GMC qualifies for Ford Blue Certified status through Ford Blue Advantage. Qualifying non-Ford vehicles can be Blue Certified when they meet the program’s age and mileage limits and pass a 139-point inspection by Ford factory-trained technicians.
