hi at 13,000pounds here in uk . bit expensive. as said there are a few cut down vw buses here that have been used as trailers . but good marketting and it is cute.
And now there's a Dinky Dub box, shorter than the original. 100% fiberglass shell, not a cut-up van. I'm surprised that VW doesn't have copyright concerns. http://dub-box-usa.com/dinky-dub/
One with unfinished interior costs $8000, delivery starts in August. The company invites custom work.
I can see one of these as a camper on a truck with flatbed.
