The 2019 GMC Sierra is here, though we've only seen the two top-tier trims, SLT and Denali. As past spy shots show, the Chevy Silverado's corporate sibling has more on the way. We now have a new batch of images showing what looks like the new All Terrain package, sort of a GMC equivalent to the Silverado's Trail Boss guise.
