Overland Expo is creating what it calls the ultimate land vehicle by taking a 2022 GMC Sierra 1500 AT4X and overhauling the truck with rugged components from the organization’s suppliers. The modified pickup makes its debut today at Overland Expo West in Flagstaff, Arizona.
The most obvious modification to this Sierra 1500 AT4X is to remove the cargo bed from the pickup and replace it with a 6.4-foot-long bed topped with a 3.0-foot-long canopy. These pieces hold all sorts of off-road gear, like an 8.0-gallon water tank, storage bins and a full-length drawer.
A roof rack holds a bank of Rigid Adapt XP lights. There is also an extendable awning up there to enjoy the shade while resting after the adventure. Don’t worry about losing touch with the world as a GMRS radio, Zoleo satellite communicator and cellular signal booster are on the roof.
If the truck gets stuck, the roof rack carries recovery equipment. Equipment includes scrap boards, a jack, and a bag containing an axe, shovel, and other tools.
To enjoy some refreshments, the canopy contains a refrigerator. It is powered by a solar panel on the roof feeding two lithium-ion batteries. There is also a camping kitchen and an outdoor shower.
The truck rolls on 17-inch wheels with Firestone Destination M/T2 tires around them. An on-board air system allows the rider to inflate them to the correct pressure for the conditions
The only powertrain tweak to the Sierra 1500 AT4X is a MagnaFlow cat-back exhaust.
Following its Flagstaff debut, the rugged truck will make appearances at Overland Expo events in Redmond, Oregon; Loveland, Colorado; and Arrington, Virginia.
The Sierra 1500 AT4X is a new addition to the truck lineup for the 2022 model year. As the name suggests, this trim sits above the already rugged AT4 grade. It is equipped with Multimatic DSSV slide dampers. The new springs increase wheel travel by 1.97 inches (50 millimeters) in the front and 0.98 inches (25 millimeters) in the rear. In addition, there are front and rear electronic locking differentials.
