NPR doesn't really say so, but this thing really is a 5er and not a 'tiny house'!! http://www.npr.org/2013/12/27/257560971/architects-dream-house-less-than-200-square-feet
I often wonder what happened to the frame of the trailer I lost in 2009 to a blowover, assuming that it was not twisted beyond use.
It had a set of Michelin XPS Ribs, with plenty of life, on it, a Trail Air pinbox with a new bladder for the heavy trailer, wet bolts, Trail Air center point spring hanger system, not much else left of it when towed away.
