2019 GMC Sierra 3500HD Denali

This 2019 GMC Sierra 3500HD Denali Crew Cab 4x4 brings together the kind of heavy-duty capability serious truck buyers demand with the upscale comfort and technology that make the Denali name special.

Finished in Onyx Black with a Jet Black interior, this clean, low-mileage Sierra has just 54,004 miles and is powered by the legendary Duramax 6.6L Turbo Diesel V8, producing an impressive 445 horsepower and 910 lb-ft of torque. Whether you're towing a fifth-wheel (up to 20,000 lbs.), hauling equipment, or simply want the confidence of a properly equipped 1-ton 4x4, this Sierra has the muscle to get the job done.

And unlike a basic work truck, the Denali interior makes every mile considerably more enjoyable. Settle into the heated and ventilated leather front bucket seats, grab the heated steering wheel, and enjoy the comfort of dual-zone automatic climate control. The power-adjustable pedals allow you to dial in your ideal driving position, while the power sliding rear window adds another layer of convenience.

Technology is equally well represented with an 8-inch touchscreen featuring navigation, plus Apple CarPlay and Android Auto for seamless smartphone integration. The premium Bose audio system provides the soundtrack, while the power sunroof brings an open-air feel to the cabin when you want it.

Outside, this Sierra is equipped for real-world hauling and towing. An Access Lorado tonneau cover provides useful bed protection and cargo security, while the swing-case toolbox adds convenient storage without consuming the entire truck bed. Towing and fifth-wheel equipment further reinforce this truck's purpose as a serious tow rig.

The Crew Cab gives passengers plenty of room, while the 4x4 chassis and Duramax powertrain provide the capability expected from a Sierra 3500HD. It's a truck equally at home pulling a fifth-wheel across the country, hauling equipment to the jobsite, or serving as a comfortable daily driver.

Low miles. Duramax power. Denali luxury. Crew Cab 4x4 capability. This is the kind of HD Sierra that gives you the best of both worlds: the strength to work hard and the refinement to actually enjoy the drive.
