The Ultimate Overland GMC Sierra AT4X was built by the Overland Expo with parts from many of the exhibitors at the off-road equipment show series.
The truck is based on the new Sierra AT4X, which features a high performance suspension and is powered by a 420 hp 6.2-liter V8.
The pickup has had its factory bed removed and replaced with a custom storage tray from MITS and a deployable awning attached to the roof.
