Dealer notes
This 2026 GMC Sierra 2500HD Denali Ultimate is a new four-door crew cab with a standard bed and 4WD, showing delivery miles only, and it is on the lot at Napleton Buick GMC on Northwest Highway in Crystal Lake. It arrives in Glacier White Tricoat — a three-layer pearl white — over an Alpine Umber full-grain leather interior, a combination that sets it apart from the darker palettes common on heavy-duty trucks.
The angle here is simple: this is a truck that works at the gooseneck hitch and the valet stand equally well.

At a glance: Duramax 6.6L Turbo-Diesel V8 · 10-Speed Automatic · 4WD · Crew Cab / Standard Bed · delivery miles only · Glacier White Tricoat exterior · Alpine Umber Full Grain Leather interior
The Max Trailering Package anchors the truck's heavy-duty credentials: an 11,750-lb GVWR rating and a Gooseneck/5th Wheel Prep Package that puts a hitch platform in the bed, ready to accept a gooseneck or 5th-wheel hitch without additional fabrication. Paired with the ProGrade Trailering System , Trailer Tire Pressure Monitor Sensors, Trailer Side Blind Zone Alert, and Bed View Camera with two trailer camera provisions, the truck is set up to manage a serious load from hookup to destination.
The X31 Off-Road Package (part of Preferred Equipment Group 5SB) adds all-terrain capability for getting to job sites or boat ramps that aren't entirely paved, riding on 20-inch ultra-bright machined aluminum wheels wrapped in LT275/65R20 all-terrain blackwall tires.
Inside, the Preferred Equipment Group 5SB delivers the full Denali Ultimate comfort story: heated and ventilated front bucket seats, heated second-row outboard seats, and a Safety Alert Seat, all in full-grain leather with the Signature Denali Ultimate Grille in Vader Chrome carrying the premium theme outside. A power sunroof opens the cabin, and the 13.4-inch diagonal GMC Infotainment System with Google built-in apps — navigation, voice assistance, wireless Apple CarPlay and Android Auto, and a mobile hotspot — keeps the cab connected.
The Bose Premium Series 12-Speaker System fills that cabin with sound, and HD Surround Vision along with ultrasonic front and rear park assist make moving the big crew cab in tight spaces manageable. Daily convenience items include a remote vehicle starter, keyless open and push-button start, wireless charging, a power sliding rear window with defogger, front rain-sensing wipers, 120-volt outlets at both the instrument panel and the bed, a spray-on bedliner with GMC logo, and all-weather floor liners for the first and second rows.
The floor-mounted center console holds two USB charge/data ports, with additional USB ports front and rear.
Napleton Buick GMC is at 6305 Northwest Hwy in Crystal Lake, right on US-14 and near the Metra UP-NW line — convenient for customers coming from Cary, McHenry, Algonquin, Lake in the Hills, and Huntley. We have been a family-owned group for more than 80 years, and we work to make the process straightforward rather than high-pressure.
If you haul heavy and want the interior to match the capability, this truck is worth an afternoon.
