Overland Expo 2022 GMC chose the Sierra AT4X because it is the ultimate build platform

When we drive the new 2022 GMC Sierra AT4X we like how much we are capable of running out of road. Now, the people at Overland Expo 2022 have decided to make it the basis of their final overland vehicle for display at the expo, to be held between July 8th and July 10th, later this year. We can’t think of a better way to get off the grid.

The AT4X is already the most comfortable way to go off-road for its luxurious features like nice multimeter DSSV dampers and massage seats. The changes that the Overland Expo focused on really expanded the truck’s ability to enjoy long journeys without having to return to civilization.

The most notable change is the replacement of the old pickup bed with a new flat tray with an accompanying canopy box. It is manufactured by the Australian based MITS Alloy North America and has more features than its modest appearance.

The canopy box actually has a damper system to separate vibration and flexing which can affect the tray itself. An eight-gallon water tank with an external tap is also included, and inside the canopy box, you’ll find a fully electric box.

It is powered by a solar panel mounted on top of the canopy and is powered by a REDARC RedVision Manager30. A CRX 110 refrigerator provides energy to keep food and other items cool while on the trail.

17-inch wheels from ICON wrapped with 33-inch Firestone Destination M / T2 rubber. After a long day on the trail, those tires can be aired up with an onboard compressor that also controls the air springs attached to the rear axle.

No changes have been made to the Sierra AT4X’s powertrain, but an optional MagnaFlow cat-back exhaust has been added that will provide better flow and a little more noise. Still, it’s an incredibly competitive package and it’s going to go on sale later this year.

At the end of the show season, Overland organizers say the truck will go up for auction. All proceeds will go to the Overland Expo Foundation charity.
