Brian, Correct, the state will not issue a registration for a tiny house, or a trailer with tiny house built on it. YOU CAN however, get a point to point permit to transport your tiny house one trip at a time. Also they are not issuing titles right now for Tiny Houses but it doesn't sound as if that is a problem for you right now.
Bottom line, please check with the code official in the town you hope to live tiny in and get the specifics from him/her about what they are going to require IN WRITING.
