Depends what you are looking for in the way of accomodation and facilities. I have owned all sorts from VW caravanettes through American Dayvans to what I now have which is a 3 berth Hymer with it's own seperate shower, invaluable at festivals!
What I really want is a big American one with a generator, and an island double bed, but it's all a pipe dream unless Ernie helps out.
