Looks like cheap, cheap construction. Tears up easily. Folks don't generally live in trailers like these for more than a few days/weeks at a time, but these folks were LIVING in them for months and months. I can believe that they have been damaged quite a bit.
Lean against one of those walls, and you'll put a hole through it. Open a cabinet door too aggressively, and the thing breaks off.
There's a difference between good, durable construction and cheap construction. The cheap stuff is cheap for a reason.
Since these are the same type of trailers that have literally self-destructed while sitting in fields unused (according to FEMA, at least), I wonder how much active "trashing" was involved in rendering these occupied trailers in need of repair.
Such cheap construction that mine that was new is 1989 has been lived in summers every year since then, with 3 growing children and grandchildren, whatever dogs we had over the years, and I have yet to see a hole in the wall or a cabinet door broken off.
