“Extra Heavy Duty” is a good way to describe GM’s all-new line of three-quarter and one ton plus haulers; more than ready for today’s work hard, play harder mindset.

Following the light duty Chevy Silverado and GMC Sierra 1500 redesigns, these 2500 and 3500 Heavy Duty pickups have all new bodywork. But, these lane-spanning behemoths aren’t just for show.

Capabilities jump for a max payload of 7,374 pounds, and 23,200 pound trailer tow limit. Both best in class. Heaviest loads demand the carryover 6.6 liter Duramax turbo-diesel V8 with 397 horsepower and 765 pound feet of torque.

A new Bifuel option comes to the smaller 6.0 liter V8, allowing for a switch between gasoline and compressed natural gas. The FlexFuel V8 carries over, as well.

Big changes come to interior and ride quality for both Chevy and GMC. With storage already plentiful, comfort takes priority this go-around. Road harshness is kept to a minimum, and the revised cabin treatment reduces outside noise. GM’s current-gen infotainment finds its way in, MyLink for the Silverado and IntelliLink for Sierra; both welcomed additions.

ZACH MASKELL: If I ever needed a heavy duty truck, this is definitely something I’d be looking into. It’s got super comfortable seats, a very quiet cabin, exhaust brake option, it’s got the rear trailer sway control…I mean this is just something you’d have to look into if this suites your needs.

JOHN DAVIS: Available in a wide variety of powertrain, cab, and bed combos, the 2015 Silverado HD and Sierra HD lineups start around $31,000. But, from there the sky is almost the limit.
