I used to live in Florida and returned last winter due to my father's illness. Work was very difficult to find and we struggled. I do suggest you consider the Okeechobee area-less than two hours from Tampa. There are many RV resorts there and it is much cheaper to live and work there.
Workamper is currently showing at least two positions near there.
one is here in Clewiston
2004 Nissan Titan, 5.6L Big tow
2007 Forest River Salem 26TBSSLE
always myself of course "> Full-Timing it!
