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 AT4 sits above the SLE and SLT but below the Denali, adding off-road hardware like skid plates and a two-speed transfer case. The AT4's unique suspension and Rancho shocks give it a more composed ride on rough trails than the SLT, at the cost of a stiffer highway feel.
