We have just had our conversion completed by CustomHaus in Swindon (used to be called Big V Campers) - fairly local to us and recommended by a friend before we started. I would definitely recommend them. We're really pleased with it although it is still early days. Communication was good and the itemised breakdown of everything meant we knew exactly what we were paying and what it was for. They did the conversion, respray, poptop, body kit, wheels and suspension.
