We had to chance to get up close and personal with a brand-new 2015 All Terrain Heavy Duty at the recent Midwestern Automotive Media Association Rally in Wisconsin, so we thought you might like to see the truck in more detail. This trim package fills out the pickup truck lineup (All Terrain is now offered on Canyon, Sierra 1500, and now Sierra HD models) yet has little in common with the impressive All Terrain HD Concept GMC showcased several years ago. In fact, our video tours of the concept truck are still quite popular. We still have hope this new trim will eventually evolve in that general direction.
In the meantime, we thought you'd like to see a few more angles and details of the 2015 HD version, so we've added a few more here and a full photo gallery on our Facebook page. Pricing will be released closer to the All Terrain's on-sale date in fall. Click here to see our All Terrain HD Facebook gallery.
