Details such as grillework that extends into the scalloped headlights, more defined wheel competently arches, and a blistered hood present GMCs 2500 and 3500 heavy-duty pickup trucks a rugged handsomeness.

Fast forward to 2019, and GMC has launched a truck called the GMC Sierra HD AT4 that is muscular, can travel off-road without showing its ’jungli-ness’, and has an interior that can put well-loaded sedans and SUVs to shame. We finally have a heavy duty version of the Sierra AT4, so let’s check it out, shall we?
