I couldn't get a picture, but yesterday I saw a Volkswagen California camper van, two-tone white over green, either a post-facelift T5 or a pre-facelift T6. Either way, not a model sold in the US and less than 25 years old, so it doesn't belong here. It had a sliding door on the left-hand side; I don't know if that means it was right-hand drive or if the California could be optioned with dual sliding doors.

I couldn't see the license plate, but it did have a bunch of stickers on it from various destinations. I think it was a European tourist on an American road trip.
