This GMC 3500 AT4 checks every box — factory 2-inch lift, aggressive styling, and true off-road capability. The interior is stacked with upgrades: Bose premium sound, memory seating, a heads-up display, and a full 360-degree bird’s-eye camera. Plus, the factory fifth-wheel prep means it’s ready to tow a camper right out of the gate. This thing is built for work — and comfort #at43500 #offroadtrucks #vehicletechnology | Auto Town GMC
