I thought about buying/building a tiny house and then I decided to buy an RV instead for full time living. It's easier to move from point A to point B.
A tiny house would be cool if I wanted to stay in one place longer. They often have really cool design features. Zoning can be tricky. I may go that route in the future when it's time to settle down more. I'm on the younger end of the spectrum for full timers. I may never want to settle down. ;)
