Full-size pickup trucks with heavy-duty capabilities serve businesses and outdoor enthusiasts alike. The 2019 GMC Sierra 2500HD shares its chassis with the light-duty Sierra 1500, and builds on that model by delivering outstanding payload and trailering capacity. It is a ruggedly handsome truck, although you’ll pay handsomely for one dressed in Denali trim.

Choosing Your Sierra 2500HD
The 2019 GMC Sierra 2500HD is offered in double cab and crew cab models along with 6.5- and 8-foot bed boxes options.
GMC offers a pair of V8 engine choices. A 6.0-liter gasoline V8 engine generates 360 horsepower and 380 pound-feet of torque. It works with a six-speed automatic transmission. The second engine choice is a 6.6-liter turbo-diesel V8 engine. This one makes 445 horsepower and 910 pound-feet of torque and is paired with a heavy-duty six-speed automatic transmission.
The 2019 Sierra 2500HD comes in four trims: Sierra, SLE, SLT and Sierra Denali. Shoppers have a choice of rear-wheel drive or four-wheel drive. This truck has a payload capacity of up to 3,534 pounds and a towing capacity of up to 18,100 pounds. The fuel economy numbers are not published.
Standard equipment includes HID headlights with LED accent lights, recovery hooks, 17-inch wheels and an easy-drop tailgate. Inside, the Sierra 2500HD has a six-speaker audio system, tilt steering and air conditioning.
GMC offers several packages, depending on the trim. A Convenience Package ($835 with remote keyless entry, a remote locking tailgate and power-controlled heated side mirrors) and a Convenience Plus Package ($1,885, which builds on the base package by adding LED cargo box lighting, a 110-volt outlet, trailering equipment and OnStar) are the two most popular choices.
An Essentials Package ($1,295, chromed assist steps, a soft-folding tonneau cover and an all-weather floor liner) is another choice. GMC also supplies a Gooseneck/5th Wheel Prep Package ($370), Hitch Package ($295) and a Protection Package ($385).
Beginning with the SLE trim, there is a Cargo Convenience Package ($410, all-weather floor mats, underseat storage and a front console organizer.) Two important package options accompany the SLT trim. A Duramax Plus Package ($10,330 brings in the turbo-diesel engine, upgraded transmission, an engine block heater, an upgraded rear axle ratio, front and rear park assist, a Bose audio system, navigation and heated side vertical trailering mirrors.) There is also the 2500HD SLT Gas Premium Package ($3,840, with spray-on bedliner, a rear sliding power window, front floor console and front leather-appointed bucket seats). This trim also has a Driver Alert Package ($845 with front and rear park assist, forward collision alert, a safety alert seat and lane departure warning.)
The GMC Sierra 2500HD is the complete package, although if you need even more pulling power or a dual-wheel rear axle, then consider the Sierra 3500HD. As for the model at hand, most shoppers prefer the Crew Cab and its roomy interior. We recommend starting your search with the SLE as it offers improved seating choices, including cloth seats with superior comfort and support.
