This is just a quick suggestion for new US routes and when the preservation crew looks at current US routes - we really do not have that many RVs here. They are really prominent on the Peninsula Corridor, you see multiple on every road. As a California native myself I have seen maybe 10 in the past year. They are definitely around, but not on the suburban streets of the Bay Area or Long Island. And even in places where they are more common you still would not see them every 4th vehicle.
Same for school buses! They are not the face of North American public road transport, and definitely not as common as they are in game.
