Exterior and Build Details
Originally finished in Frost White, the truck now wears metallic orange. Quad headlights, roof marker lights, and stainless camper mirrors emphasize utility. Diamond-plate running boards, a cowl hood, and a chrome bumper add presence. A 50-gallon aluminum fuel cell sits in the bed.
