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 SLT and below the Denali, adding off-road hardware like an automatic locking rear differential and skid plates. The AT4's suspension is tuned for dirt roads, so expect a firmer ride on pavement than the Denali's air springs would give you.
