The Hammer: GMSV × Big Dog Builds 2500HD Show Truck

When GMSV asked Big Dog Builds for a show truck that hits as hard as it looks, we delivered The Hammer. Lakeshore Blue Chevy 2500HD on a BDS 5-inch lift, 37s on Fuel Covert wheels, our V1 prototype steel front bar, a colour-coded Norweld tray + canopy combo, and a 5,828kg NB2 GVM that lets the whole rig stay legal at full Aussie touring weight. Debuted on the GMSV stand at the Brisbane National 4×4 Show. Dean walks you front to back — what's on it, why it's there, and where you'd dial it back if you don't need 37s under the wheel arches.
