2022 Overland Expo Ultimate Vehicle Build | 2022 GMC Sierra 1500 AT4X

Exclusively utilizing parts and expertise from our exhibitors, this GMC Sierra 1500 AT4X embodies Overland Expo’s vision of the ultimate overland vehicle. This truck was selected as the base vehicle for its potent V8, techie and luxurious cabin, and capable four-wheel drive system that features front and rear electronically locking differentials. The stock pickup truck bed was removed and replaced with a tray and three-foot canopy from MITS Alloy North America. Inside the three-foot — i.e. “half” or “dog box” — canopy is a REDARC RedVision Manager30, which manages a solar panel affixed to the canopy roof and routes power from the solar panel in to two Battle Born lithium-ion batteries. These batteries power the standup-style CRX 110 fridge from Dometic. Inside the canopy is a Camp Kitchen from Green Goat Outdoors, AluBox from Equipt, and Geyser Systems shower. Behind the half canopy lies a two-person Outbreak 1550 Swag ground tent from 23 ZERO. Further modifications include 17-inch alloy wheels from ICON Alloys, which are wrapped in 33× Firestone Destination M/T2 tires. After deflating the tires, Viair’s Expedition onboard air system will quickly re-inflate the tires to optimal pressure. The GMC’s 420-horsepower V8 comes to life with a roar thanks to a cat-back MagnaFlow performance exhaust system, which is tucked up under the body and clear of trail obstacles. Several sets of Rigid Adapt XP lights mounted at the bottom of both A-pillars as well as atop the Rhino Rack Pioneer platform rack over the trucks’ cab illuminate the trail after sundown. Shade, respite from the midday sun, is created by the Rhino Rack Sunseeker 2.0 awning that is also affixed to the Pioneer rack. A second AluBox is mounted atop the Pioneer rack, which holds the rig’s recovery gear. Next to that are two waterproof dry bags from 3D, which hold personal gear. Recovery duty is handled by Go Treads traction boards, Safe Jack bottle jack, and the Max Tool Kit from Forrest Tool. Passengers will stay safe and well connected to friends and family, even when in remote regions, with the MXT575 GMRS radio from Midland, ZOLEO Satellite Communicator, and weBoost cell signal booster. All components were expertly installed by MULE Expedition Outfitters. For more on the Ultimate Overland Build, visit
