For a long time i looked for one without luck and when i did finally find one the price was so high that it was ridiculous so never purchased one. I built my own unit that slides out. It gives me half the cabin space again but to be honest, more often than not i don’t open it up as it is nicer sitting out side under the awning. If i had my time again i would have just been happy with a VW Californian with some minor modifications. Buying an old VW is fraught with potential problems. As a matter of interest, how much are they asking?
