The tiny homes that I have seen on tv do not appeal to me at all. Some of them make me feel claustrophobic at the thought of living there full time. (I am not looking to down size, but certainly understand the appeal of a small - not tiny house.)
I recall seeing one of those shows, where the little girl had to do her homework in her bunk bed - and there was not enough room for her to even sit up straight, she had to hunch over.
I had no idea of the additional problems listed by OP until I read this.
I do not view trailers (which of course come in a variety of sizes, for a variety of purposes) the same as those tiny houses.
Do the math.
