Dealer notes
In transit and arriving soon at Napleton Chevrolet Buick GMC in Beaver Dam, WI, this 2026 GMC Sierra 3500HD SLE is a new two-door regular cab, long bed, four-wheel-drive diesel truck dressed in Sterling Metallic — a cool, medium metallic silver — with a Jet Black cloth interior. It's built from the ground up for buyers who want to work hard, tow heavy, and handle terrain that would stop a lesser truck in its tracks.

The capability story here is broad and deliberate. The X31 Off-Road Package adds off-road suspension, hill descent control, and skid plates so the truck handles rough ground with confidence.
The Snow Plow Prep/Camper Package brings a 220-amp alternator and additional skid plates — the kind of spec sheet a contractor or property owner looks for before buying. The Gooseneck/5th Wheel Prep Package is in the build, making this truck ready for serious trailer work from day one.
LT275/70R18E all-terrain tires on 18-inch machined aluminum wheels and outside power-adjustable vertical trailering mirrors with heated and auto-dimming upper glass round out the working end. An exhaust brake is also included, an important addition when hauling heavy loads downhill.
The factory-applied spray-on bedliner and black tubular assist steps are on the truck as delivered.
The SLE Convenience Package adds a 10-way power driver seat with lumbar, dual-zone automatic climate control, manual tilt-and-telescoping steering column, and LED fog lamps. The Remote Start Package covers remote vehicle start, electric rear-window defogger, and an unauthorized entry theft-deterrent system — practical additions for Wisconsin winters.
Inside, the 13.4-inch diagonal premium GMC infotainment system supports wireless phone projection, and the Preferred Equipment Group 3SA adds keyless open and push-button start, SiriusXM with 360L trial subscription, a mobile hotspot, steering wheel audio controls, and both a 120-volt bed-mounted and a 120-volt instrument panel power outlet. Two charge/data USB ports and a winter grille cover round out the equipment list.
The Sierra HD Pro Safety Plus Package brings front and rear ultrasonic park assist, rear cross traffic alert, trailer side blind zone alert, and the in-vehicle trailering app, alongside the base Sierra HD Pro Safety suite that includes forward collision mitigation, pedestrian impact prevention, rear camera, and brake assist. An engine block heater is also part of the build.
