I'm searching dealer inventory, trying to find the "unicorn" truck that I want (specific options). One of my must-haves is the Level 1 Equipment Group in the Limited trim. I've noticed that the contents of the Level 1 Equipment Group seem to be all over the place. Sometimes it includes SiriusXM 360L and sometimes it doesn't. Sometimes it includes Surround View and sometimes it doesn't (regardless of the towing mirrors). Sometimes it includes ventilated rear seats and sometimes it doesn't. Are some of these features late-availability, and some of these trucks earlier builds? Or are the window stickers inconsistent? Many of these trucks are upwards of 50 miles away from me, and I don't want to drive to see if it it doesn't have the features I want. I've called the dealers and they don't seem to have any idea what I'm talking about. I can't be the only one that's noticed this, so I figured I would throw the question out there. Thanks in advance for any feedback!
