Yeah, there's quite a few mobile home parks in the Fort Myers area, many of which are on San Carlos Island. I can only imagine that most of those were completely wiped out. I know that a few of them had a fair amount of snowbirds with RVs, so the hope is that many of them were either not in the area yet for the winter or were able to evacuate with their RVs. Any fixed mobile homes would have been in the flood zone and wouldn't have stood a chance with the storm surge that area faced.
On a side note - it's Fort
Myers, not Meyers.
