SEMA is a place of wild extremes and outlandish fantasy. Custom vehicles sit in the Las Vegas convention center with candy apple paint jobs, insane lift kits, and high-horsepower add-ons. The Chevy Silverado 2500HD Alaskan Edition Concept is not one of those builds. In fact, Chevy brought this concept to preview a production truck. For 2017, the Silverado 2500HD can be had with the Alaskan Edition – a snow plow prep package.
