FEMA may or may not but lots of snowbirds will need replacements and some other locals will want a trailer while they rebuild.
It will be much different as the flooding is largely already done, except for a few key areas around resevours. Happens when you build above sea level.
Big difference will be the type of trailers. The FEMA trailers were horrid things. I suspect the manufacturers didn't want competition when they came back on the used market so they were all plain white with minimal small windows and no big company logos. If it's private individuals buying, they won't accept the standard FEMA trailer.
