Yup, just stick around, and you can learn all there is to know (well, almost!) about Airstreams. As noted above, they're not for everyone - they are terrific if you want to travel, but not as roomy as a 5er if you're gonna' sit in one place. Yup, no basement, smallish tanks, "odd" curving walls, but lots of style and an iconic history.
If you really get interested, drop in to the nearest Forums or WBCCI rally and get a tour of a bunch of coaches and see what might work for you and your travel style.
