      DEALER COMMENTS:

      Somebody ordered a one-ton AT4 with the gooseneck prep.

      That is the tell. The hitch platform in the bed, the stamped holes with the caps still in them, the bed-mounted seven-pin - nobody specifies that without a fifth wheel or a gooseneck already sitting at home. The L5P Duramax and 975 lb-ft behind it are what pulls it.

      Single rear wheels, so it still parks in a normal space and threads a jobsite gate like a half-ton while carrying the one-ton rating.

      AT4 on top of a truck this serious is the good, odd part: red recovery hooks, off-road high-clearance steps, a sunroof, perforated leather in Jet Black with Kalahari accents.

      Come hook a trailer to it. eawcars.com
