A rugged, post-apocalyptic heavy-duty truck with massive off-road wheels, reinforced steel armor plating, spiked grills, rusted textures, exposed engine parts, and mounted weapons like a turret or harpoon. The truck should look battle-worn, with patchwork metal, scavenged parts, and heavy suspension. Design should blend Mad Max style with military utility. Include a dirty, dusty look and a roll cage cabin with survival gear.
