Yeah - I saw that on "The List".
I'd suspect that those assets are already pre-plated, and it was refreshing to see one that wasn't an EU plate or New York - both seem to be very common on standard assets and will show up regardless of the VN setting. If you go to a U-Haul lot in Texas, you'll find all manner of California plated trucks - there have been news articles about how many vehicles are leaving CA (and a few other heavily taxed, poorly run states) and how big of a shortage moving companies are having, as well as the expense incurred to get trucks back into high exodus cities and states since there isn't a strong flow of people coming into the state from elsewhere.
Then again, given Kelly's business, it's just as likely they are fake or stolen.
