Golf MK1 Tischer?

Hi

New to this forum and Vws but I've become interested in the Tischer demountable camper. I was meant to go and see one recently but by the time I could it had gone! Does anybody know anything about them (they do appear to be rather rare) as most of them seem to be using a MK1 golf  pick-up as the base vehicle. How do they handle, what sort of MPG do you get, etc, etc.

regards

youll be lucky...
