2020 GMC Sierra 3500HD

The GMC Sierra 3500HD comes in five different trim levels: the Sierra, SLE, SLT, AT4, and Denali. All five will give you a variety of different cab and box options, so you can design your perfect truck. Once you choose your ideal combination, take a step up on the side bed step. It allows you to see the bed safely from the side of the truck. There is also a step on the corner of the rear bumper for easy access.

The tailgate has six different functions and adjusts with ease to fit your load. It opens traditionally, but you can add a load stop so larger items stay in place when you're on the road. For easier access, the inner gate folds down into a step. If you need a larger step, remove your trailer hitch and the tailgate becomes a full-width step that handles up to 375 pounds. The inner gate stop keeps anything on the second level from falling out. Fold the inner gate stop down, and you have a perfect surface for doing paperwork or using your laptop.

You'll have your choice between a gas or diesel engine as you design your perfect truck. If you choose the standard gas engine, it is a 6.6-liter V-8 block that runs on regular unleaded fuel. It uses direct fuel injection to give you 401 horsepower and 464 pound-feet of torque.

Diesel fans will enjoy the power of a 6.6-liter Duramax turbo-diesel block. This powerful engine produces 445 horsepower and 910 pound-feet of torque with common-rail direct fuel injection.

All of the trims pull their fair share of weight. If you choose the Sierra, SLE, or SLT options, you'll be able to tow 35,500 pounds and have a maximum payload capacity of 7,442 pounds. Do you want an athletic truck? The AT4 tows a maximum of 21,300 pounds and has a payload of 4,398 pounds. It is ideal for off-road adventures with the addition of a 2-inch factory-installed suspension lift. The skid plates protect sensitive components while you drive over a variety of terrains. Denali owners enjoy a maximum 31,180-pound tow limit and a payload of 6,610 pounds.

The interior of your 2020 GMC Sierra 3500HD keeps you and your friends comfortable, no matter where your adventure takes you. The crew cab gives you 43 inches of front-seat headroom and 44.5 inches of legroom. Add the available heated front seats for a comfortable ride on a cold day. They are standard in the Denali. The driver seat sits taller for more comfort on long drives or while you are towing.
