The #GMCSierra has always been the 3rd best-selling truck in America right behind the Chevy Silverado and Ford F-150. For 2020, GMC is giving the #SierraHD a complete redo on the outside, a new frame underneath, and some pretty advance industry first features for truck buyers who plan to do a lot of towing. The light duty #Sierra also benefits from a 5th engine option, a 3.0L #Duramax #diesel inline 6-cylinder engine that offers up the most HP in the class at 277 and a stump pulling 460 lb-ft of torque. It all makes for the most capable Sierra that #GMC has ever made with the ability to tow up to 35,500 pounds on certain HD trucks.
