That does make sense about the extra digit codes, and it looks like we have a nice amount of samples so that those making labels can pick a similar truck to theirs and likely get all the right codes, not just the short option code.

I wonder if the stickers were printed with serial number in one place and then the rest of the options done at the plant where it was built? Or maybe the serial number was put on the sheet at a later point in the process? Seems unlikely, but would love to hear the stories of how these things are inconsistent between plants.
