Dealer notes
The 2026 GMC Sierra 2500HD Denali Ultimate arrives new at Napleton Chevrolet Buick GMC in Beaver Dam with delivery miles only, finished in Onyx Black over Alpine Umber full grain leather. Among the Sierra 2500HD family on our lot, this is the trailering specialist: every camera angle, every sensor, and every data point a driver needs when hooking up something heavy is built in from the factory — and the cabin makes the miles between hitches genuinely comfortable.

Built around the hitch. The ProGrade Trailering System brings together more hardware than most competitors offer separately. HD Surround Vision and the bed-view camera with two trailer camera provisions let you monitor what is behind and beside the truck at every stage of hookup and travel.
Trailer tire pressure monitor sensors track the load in real time. Trailer Side Blind Zone Alert extends the truck's blind-spot awareness to the length of whatever you are towing.
The gooseneck/fifth-wheel prep package adds a hitch platform ready to accept either configuration, and the Snow Plow Prep/Camper Package contributes a 220-amp alternator and skid plates for demanding attachment duty. A 2-speed active transfer case and 3.42 rear axle ratio are part of the record.
LT275/65R20 all-terrain tires on 20-inch ultra-bright machined aluminum wheels complete the heavy-duty stance.
Comfort and technology that match the price of admission. The Denali Ultimate's cabin opens with front bucket seats in Alpine Umber full grain leather — heated, ventilated, and equipped with a safety-alert function — and extends that heated comfort to the second row outboard seats.
A 13.4-inch GMC infotainment display runs Google built-in apps including navigation and voice assistance, pairs with wireless Apple CarPlay and Android Auto, and connects wirelessly to the driver's phone for charging as well. The Bose Premium Series 12-speaker system handles audio.
A power sunroof, power sliding rear window with defogger, remote vehicle starter, universal home remote, and a floor-mounted center console fill out the daily-use picture. On the outside, the Signature Denali Ultimate grille in Vader Chrome sets this truck apart from every other trim in the lineup, and LED smoked amber roof marker lamps and LED cargo area lighting add presence and practicality after dark.
The spray-on bedliner carries the GMC logo, front and rear molded splash guards are fitted, and all-weather floor liners cover the first and second rows.
Napleton Chevrolet Buick GMC is on Kellom Rd. in Beaver Dam — about 45 minutes from Madison, an hour from Milwaukee, and 35 minutes from Fond du Lac, making it a straightforward drive for shoppers coming from Watertown, Columbus, Randolph, or Hartford. We have been family-owned for more than 80 years, and we run a no-pressure process from first look to final paperwork.
If you pull, haul, or need the truck to do both every week, this Sierra has the equipment to back that up — bring the trailer specs and we will walk through every connection point together.
