Best truck I have owned

I've owned every other American truck and this is my first GMC. I bought the 2500 HD Texas Edition. I absolutely love this truck. It's everything I could have hoped for and more. It is able to pull my 30' travel trailer with no problems. So now when we go out with our trailer I'll have no worries. The look and feel of the truck...

2024 GMC Sierra 2500 review: Our expert's take

By Brian Normile

What truck do you get the rancher who has everything? Something that can tow and haul, of course, because there’s work to be done on and off the ranch, but maybe something that can get a little down and dirty, too. As capable as it is off-road, the Ram Power Wagon is probably out because all that off-road capability takes away from its heavy-duty work truck abilities. Ram makes a 2500 Rebel, too, but your rancher friend is a staunch GM loyalist. If the Chevrolet Silverado HD ZR2 Bison isn’t posh enough, consider the all-new 2024 GMC Sierra HD AT4X AEV Edition. We headed to the Xoverland Ranch in Montana to put the heavy-duty off-roader through its paces (per Cars.com’s ethics policy, we pay for all travel and lodging at such manufacturer-sponsored events).

What Do You Get in a Sierra HD AT4X AEV Edition?

The foundation of the truck is a 2024 Sierra 2500 three-quarter-ton pickup, and buyers can choose either the standard 6.6-liter gasoline V-8 good for 401 horsepower and 464 pounds-feet of torque or the optional turbo-diesel 6.6-liter Duramax V-8, making a healthier 470 hp and 975 pounds-feet. Either way, your only transmission option is an Allison 10-speed automatic. Four-wheel drive is also standard.

Like other AT4X models in GMC’s pickup lineup, the Sierra HD gets off-road-focused equipment, including a 1.5-inch lift, 35-inch mud-terrain tires, Multimatic DSSV dampers, an electronic locking rear differential, a steel skid plate for the transfer case, an aluminum front skid plate, and revised steering and suspension components.
