`Never had a microbus nor Westfailya (as I call my buddy's VW) but I did drive 200,000 miles in the `74 Volvo wagon I bought new and slept many nights in. A lot of my trips were for work. When I didn't need to be spiffy in the morning, I'd save my per-diem and camp comfortably in the wagon, sometimes in marinas or boat yards, often in hospital parking lots. Nobody bothered me, thinking I had somebody in the hospital; the bathrooms were always clean and sometimes the coffee was decent.
Later I bought a cherry Volvo 1800ES and improved it over the years, and camped in back. With the passenger seat-back flipped forward and luggage filling the void under my Thermarest, there's 6'6" stretch-out room, the dome light right there for reading, sterio within reach, with speakers on either side of my pillow. It is a little like sleeping under a coffee table. In the country on clear nights, I lay with my head under the glass hatch and star-gaze.
I still have the ES, now with some 600,000 miles on it, still running strong, looking new and handling much better than new. I've slept in public places with the car cover on, nobody the wiser, and during the day, sleeping pad and bag stow out of sight under the rear seat folded down.
By comparison the Ticket, my 22-Cruiser, seems really big.
