My 20 year old granddaughter loves the idea.
She understand that they are not RVs and not mobile.
She hopes to get one, and sell it after she makes her fortune and buy a Class A.
That way she will never get addicted to 'space' and never be stuck with utility and tax costs of a 'real house'.
Today, we are near the end of 2 1/2 weeks dental work in Mexico, sitting in a RGV snowbird RV park. Plenty of full sized mobile homes (which aint' mobile) and park models in the place along with 5ers and TTs which will never be pulled on another trip. And a scattering of newer Tiny Homes.
Some folks see the Tiny Homes as better designed/ built for permanent residences than park models or regular RVs.
No I don't see the attraction. But I'm an old sailor who still wants to visit new ports before age makes that impossible.
