Miles Overview
The 2021 Sierra 3500HD is GMC's heavy-duty pickup, built for serious towing and hauling work. It drives with the authority you expect from a heavy-duty truck, though the ride can be stiff when unloaded. The cabin is roomy and quiet, with upscale touches on higher trims like the Denali. You get a choice of regular, double, or crew cab, and the bed is built to take abuse. The SLT is the value pick in the 3500HD lineup, giving you most of the capability of a Denali without the luxury price. Its 6.6L V8 and automatic transmission deliver strong low-end torque for pulling trailers or hauling heavy loads, and the four-wheel drive adds traction on slippery sites. You can add the Convenience Package for heated seats, a heated steering wheel, and a gooseneck/ fifth-wheel trailer hitch prep package.
