It would "define a recreational vehicle as one built on a vehicular structure, not certified as a manufactured home, designed only for recreational use and not as a primary residence or for permanent occupancy." The panic ensues from the wording that would appear to prevent anyone from living full time in any home on a chassis that is not legally certified as what used to be called a mobile home but is now called a manufactured home. But it has ever been thus.

Andrew Morrison of Tiny House Build and Andrew Heben of Tent City Urbanism both do excellent analyses of the issue, explaining why this change really is not a problem for the tiny house community. (Snopes does a pretty good job too)

However Heben hits on the bigger problem that everyone in the Tiny House world has been dealing with since it started, which is nobody really knows what they are.
