Be aware that small, molded trailers are really for camping, not living in. (I say that because you compared them to tiny houses.) Insulation is definitely not sufficient for a Kansas winter. If you move around to follow mild weather... different story. One person and a dog could live in a 13' Scamp
. Okay... a small dog.
Time to start a savings plan...
Anyway, this is the right place to hang out and learn more about Scamps and their kin. Best wishes!
