Interesting. Based on those dimensions, the only height that would probably be suitable for an RV that would allow an average height person to stand up in would be the Super High Roof with an outside height of 9'2" (the high roof Sprinter is about 9'). The length options are 19' 7", 22' 5" and 24' 3".
I bet it is a long time before VW brings this vehicle to the US market.
