Dealer notes

The 2026 GMC Sierra 2500HD AT4 at Napleton Chicago Chevy Buick GMC on S. Michigan Ave. is a new crew cab 4WD pickup with delivery miles only — finished in Onyx Black over jet black perforated front leather with Kalahari accents, and built around a trailering package few heavy-duty trucks can match at any trim level.

If your work involves a gooseneck, a fifth wheel, or anything you'd rather not guess about on the road, this truck was specced for that job.

The trailering story starts with the ProGrade Trailering System and the gooseneck/fifth-wheel prep package, which provides a hitch platform ready to accept a gooseneck or fifth-wheel hitch without additional fabrication. Behind the truck, a bed-view camera with two trailer camera provisions feeds into the HD Surround Vision system, and Trailer Side Blind Zone Alert watches the flanks while you're moving.

The Preferred Equipment Group 4SB also includes trailer cam provisions and trailer viewing software, plus a 120-volt bed-mounted power outlet for tools or accessories at the work site. A 3.73 rear axle ratio and the X31 Off-Road Package — with LT275/65R20 all-terrain blackwall tires on 20-inch high-gloss black aluminum wheels and a two-speed active transfer case — keep the truck moving when the job site isn't paved.

Inside the cab, the Preferred Equipment Group 4SB adds perforated front leather seating with ventilation for the driver and front passenger and heat for both front seats and the second-row outboard positions — so the crew is comfortable whether you're running early or finishing late. The AT4 Premium Plus Package brings a power sunroof and the Technology Package.

A 13.4-inch diagonal premium GMC infotainment display runs Google Built-In apps for navigation and voice assistance, wireless Apple CarPlay and Android Auto projection, and a Bose premium seven-speaker sound system. A multicolor 15-inch diagonal head-up display, rear camera mirror, front rain-sensing wipers, ultrasonic front and rear park assist, and Safety Alert Seat round out the daily-driving experience.

The AT4 Preferred Package adds a power sliding rear window with defogger, LED smoked amber roof marker lamps, and Universal Home Remote. Keyless open and start, push-button start, remote vehicle starter, and wireless charging are all part of the 4SB package — as are spray-on bedliner with the GMC logo and rear wheelhouse liners to protect the bed and the rails.

Napleton Chicago Chevy Buick GMC is at 2720 S. Michigan Ave., Chicago — on Motor Row at 27th St., steps from McCormick Place and the Cermak–McCormick Place Green Line, and an easy drive from Bronzeville, Hyde Park, and the Loop.

We've been a family-owned group for more than 80 years and believe in a no-pressure process. When you're ready to hitch up and get to work, this AT4 is on the lot.
