2020 GMC Sierra 3500HD near Plainfield, IL

>2020 GMC Sierra 3500HD For Sale Near Plainfield, IL

The 2020 GMC Sierra 3500HD is a big truck that's made for big jobs. From hauling payloads to pulling fifth-wheels, this is one pickup that takes 'heavy duty' seriously. Here's a look at all that the 2020 GMC Sierra 3500HDs for sale near Plainfield, Illinois are capable of.

Payloads Exceeding 6,000 Pounds

For hauling without a trailer in tow, the 2020 GMC Sierra 3500HD has a maximum payload of 6,196 pounds. For perspective of just how much weight this is, the 2020 Sierra 3500HD could easily transport the 2020 Sierra 1500 if it fit in the bed. Even some versions of the 2020 Sierra 2500HD wouldn't exceed this payload capacity's maximum weight. (Some configurations of the 2020 Sierra 3500HD have slightly lower maximums than what's noted here.)

If you're regularly hauling heavy loads around town or to a construction site, a 2020 GMC Sierra 3500HD that's for sale near Plainfield, IL might make sense simply because of its payload capacity. With this high of a weight limit, even bricks, concrete and rocks can be taken as sizeable loads.

Conventional Towing of 20,000 Pounds

When you have a trailer in tow, the 2020 GMC Sierra 3500HD again comes through. Specifically, it'll go through almost anything with capable four-wheel drive -- and it'll haul a lot of weight on the hitch.

Conventional towing capacity tops out at an even 20,000 pounds, which is more than what almost anyone needs. Whether you're hauling a boat, camper or work trailer, that'd have to be one huge trailer to exceed this weight maximum.

Fifth-Wheel Towing Exceeding 30,000 Pounds

If you do have a trailer that's more than the conventional towing limit of 20,000 pounds, the 2020 GMC Sierra 3500HDs for sale near Plainfield, IL are still up to the task. When outfitted for a fifth-wheel or gooseneck, maximum towing capabilities increase to as much as 31,760 pounds. Simply put, that's a lot of weight. Even some tractor-trailers don't weigh that much when unloaded.

Innovative Camera System for Towing

Moreover, the 2020 GMC Sierra 3500HD doesn't just have the raw power to haul, but it also comes with a camera system that makes towing easier. The class-leading available camera system affords 15 different views -- including a transparent trailer view that shows what's behind the truck as if a trailer weren't even connected.
