We enjoy watching the "tiny house" shows (and there are quite a few of them!) However, we always think they would be much better off in an RV, since storage and plumbing are so much easier to work with in standard RVs. I think the movement grew out of some of the younger folks finding homebuying too expensive, but not wanting to be seen as living in a "trailer." I'm sure it's a passing fad; for one thing, as more and more of them show up, communities are going to start passing more restrictive zoning laws.
