I wonder how towable it is. I have friends who have RVs that are much more expensive than this portable house, and the RVs are not as nice inside.
We talked about getting or building a tiny house on wheels instead but we settled on the travel trailer because it should be easier to resell once we've built our house.
If you want to live in a tiny house and it's not just temporary it seems easier and cheaper to just build it on the dirt. I could see these houses on wheels coming in handy if you don't own your land or have other building restrictions but still plan to be there for awhile. I wouldn't imagine these would be good for frequent moves since none of the interior is designed to "batten down" and the transport could stress the (often) wood frame classical construction.
