Dealer notes
The 2026 GMC Sierra 2500HD SLT is a new, four-door crew cab with standard bed and 4WD, here at Napleton Chevrolet Buick GMC in Beaver Dam with delivery miles only. This one arrives in Summit White over Jet Black perforated leather-appointed front outboard seating, and it earns its place as the gas-powered answer to a serious work-and-tow build: a 6.6L V8, X31 Off-Road hardware, a full trailering camera suite, and a cabin equipped to the level most drivers would order on a diesel.

Two X31 packages define how this truck is set up for work. The X31 Off-Road Package adds off-road suspension, hill descent control, and skid plates. The X31 Off-Road and Protection Package layers on 20-inch bright face wheels with dark painted pockets, all-terrain LT275/65R20 tires, a spray-on pickup bedliner with GMC logo, and all-weather floor liners — protection on the job site built into the original sticker, not added afterward.
The gooseneck/fifth-wheel prep package includes a hitch platform ready to accept a gooseneck or fifth-wheel hitch. ProGrade Trailering System is included, and so is the Sierra HD Pro Safety Plus Package , which brings HD Surround Vision, a bed-view camera with two trailer camera provisions, trailer camera provisions and trailer viewing software, trailer side blind zone alert, ultrasonic front and rear park assist, rear cross traffic alert, and a safety alert seat.
The 13.4-inch diagonal GMC Infotainment System with Google built-in navigation and voice assistance keeps the route and the trailer status visible on one screen.
Inside, the SLT Convenience Package delivers ventilated driver and front passenger seats alongside heated driver and front passenger seats (from the Preferred Equipment Group), heated second-row outboard seats from the SLT Preferred Package , wireless charging, and a Bose Premium 7-speaker sound system with RichBass woofer. Adaptive cruise control, remote vehicle starter system, front rain-sensing wipers, a power sliding rear window with defogger, keyless open and start with push-button start, wireless Apple CarPlay and Android Auto, a mobile hotspot, and 120-volt power outlets in the bed and instrument panel round out a cabin that doesn't ask you to choose between comfort and capability.
The GMC MultiPro tailgate gives you multiple configurations for loading and jobsite use.
We're at N8167 Kellom Rd. in Beaver Dam — about 35 minutes from Fond du Lac, 45 minutes from Madison, and roughly an hour from West Bend and Hartford. Shoppers from Waupun and Portage make the drive regularly, too.
Napleton has been family-owned for more than 80 years, and we keep the process straightforward. If you're ready to put a bed full of gear behind a V8 that's already set up for it, this Sierra is worth a look.
