Out of all the equipment listings I have found so far and parsed through with some Python (17,587 of them right now) it seems the tech features are potentially a big bottleneck.
I ordered a Laramie with the digital mirror, surround view, trailer surround view, and blindspot monitoring.
None of the window stickers I've found include all of those options on a Laramie. Except for two of the development trucks which are sequence numbers 6 and 129.
It makes me feel a little bit better that while I'm seeing trucks ordered 2 months after mine, there is certainly some logic to it.
I'm trying to make this data available in a spreadsheet so that anyone can filter it and figure out if trucks have been built after their sequence number with all the same options. Just need enough time to do it.
