Meet the black 2018 GMC Sierra 3500HD—a used heavy-duty truck that’s built to work hard and clean up even better. With 4WD and a 6.6L V8 OHV 16 diesel under the hood, it’s the kind of pickup that feels ready for early starts, long hauls, and whatever the week throws at you. Inside, it brings serious comfort to the job: leather seating with both heated and cooled front seats, supportive power adjustment and lumbar help, and a telescopic steering column so you can dial in your perfect driving position. Set the cruise control, roll down the power windows, and enjoy the quiet confidence of a cabin designed for real road time. On the outside, alloy wheels, fog lights, and high-intensity discharge headlights give it a bold, capable look that matches its truck-tough attitude. Safety and peace of mind come along for the ride too, thanks to ABS and a full lineup of airbags, plus child safety door locks and an anti-theft system. And when you’re ready to take a closer look, you’ll be glad to know a CARFAX report is available for this Sierra 3500HD.
