And then there is the Vixen, with a BMW turbo diesel
engine.

Yeah, I thought about mentioning that in my last post. I bet the reliability of those makes the Vanagon waterboxer look like a Toyota! I was in one ( a Vixen) at an RV show back in the days when they were new-as I recall it was very cramped inside, way too much crammed into it, just like the van based campers out there today, like the Roadtek. At 6'4" I really get a laugh out of the "bathrooms" they put in these campers!   Jeff
