Trust me, man, I gots the time and... the passion. I do and have lived in small spaces and the best thing is to have storage and custom stuff. The 300 square foot house I live in now has none of those things and it is a nightmare. After four years of carpenter ants, casement moths, black mold, carpet beetles, squirrels, wasps etc. I'm ready to get out.
I already have a basic list of what the innards of my TT will look like and what I need. I'm looking for a solid cheap one right now and this one fell into my lap. I'm still debating but the brand new underthings and the outer condition is tempting.
