Spotted: The GMC Sierra HD AT4X Looks Big and Mean
It's easy to spot the GMC Sierra HD AT4X as it barrels down the highway.
With its beefy body and black grille, this full-size pickup truck looks big and mean.
Onlookers may not realize the truck packs plenty of features underneath that tough exterior.
An impressive 12-inch touchscreen display puts a world of entertainment at drivers' fingertips, while air suspension keeps them comfortable on the ride.
An upgraded trailering package with high-tech cameras gives the Sierra HD extra confidence for all sorts of adventures.
But one look is enough to tell you this vehicle has serious capability and presence on the road.
Ram 1500 TRX and a Ford F-150 Raptor R were spotted cruising together. - USA Vehicle
