Chausson vans are very popular on the continent and you see plenty of them around. The Tranny is tried and tested although as posted can be a bit noisey. The main reason few converters use them in the UK is down to basics - "price" in order I suppose the VW is the dearest, then the Tranny the Fiat/Peugeot(same van) is the cheapest so thats why it holds around 70% of the new build market
