The AT4X American Expedition Vehicles Edition adds an elite air to its ruggedness with AEV-stamped steel bumpers, AEV skid plates, and a boron steel front approach. Meanwhile, the Denali and Denali Ultimate redefine luxury among full-size trucks. The Denali Ultimate in particular boasts an exclusive Vader Chrome grille, power-deployable assist steps, and domineering 22-inch 7-spoke premium wheels.
