Mine came with a title. I don't think it makes any reference to FEMA.
It is possible that there was no water damage until it was moved and titled.
When I went to inspect before the auction. , I found campers that were unused, plastic wrapped and labeled. Some of them had soft spots at the front door. My guess is it was rain. Google FEMA trailers there are images of the storage facilities with what looks like thousands of campers.
Imagine the irony of losing your FEMA camper to a flood.
my buddies and I picked a spot along the Cumberland to put our campers. The spot was under 20ft of water in last years flood. Good thing we had not had time to move them in.
