I also had a couple VW buses back in the day (not to mention numerous VW Bugs). Must have been the seeds of the bigger bus to come.
One of the best times of my life was touring the United States in a 1967 VW bus/camper one summer during college back in the late 1980's. It had the split windshield, metal dash, pop-up camper roof... classic. I later got a 1973 bus into which I put a camper interior. That bus was a party-mobile, and really gave me an appreciation for having my living room and bedroom wherever I was.
