We’ve already shared all kinds of information about the upcoming 2020 GM HD trucks, including the revamped gasoline engine, integrated box-side step, and spy shots galore. And now, we just got our hands on the very first pictures of the 2020 GMC Sierra HD in the dual rear wheel (dually) body style.
The photos show the sculpted design applied to the dually body style, with very wide body panels over the rear wheel wells. The wide-body design continues to incorporate the side box step ahead of the rear wheels, providing convenient access to the box from the side of the truck.
The shots also give us an idea of the position of the integrated side step on models with longer beds: the integrated side step will always be placed at the front-most corner of the rear box, regardless of bed length.
Notably, the 2020 GMC Sierra HD also has tri-fold wheel wells. The design was initially introduced on the HD’s smaller brother – the 2019 GMC Sierra 1500.
Expect the all-new, 2020 GMC Sierra HD to ride on the new GM T1 platform, feature an updated powertrain lineup (with an all-new gasoline engine), and go on sale in the middle of the 2019 calendar year as a 2020 model year vehicle.
