Besides, wherever those trailers end up, they'll be there FOREVER (or until they decay into corroded scraps of metal).
I gather you haven't seen them up close and personal? They won't last that long. They are very cheaply made.
August 2002:
Thirty families are asked to leave their FEMA trailers near Tarboro, almost three years after Hurricane Floyd forced them from their homes. The government-funded trailers were initially intended to house flood victims for up to eighteen months, but the deadline for ending the program was extended several times.
Not so.
And FWIW, the FEMA trailer parks in Pensacola are neat, clean, and well maintained.
