Snowbird Test the Waters Options?

I'm a former RVer but out of the game for a few years and miss it. My new wife and I have been discussing ways to beat the winter and talked about buying a place in Florida and so forth. But I think a better option would be to purchase a class A and set up camp down there from Jan-April each year.

I mostly work at home with some travel, so I'd have to be near a major airport. She's an RN who is taking a break after her last assignment to finish up her Masters (just a few classes left). She will probably do per diem/temp and/or travel nursing so that may work out well for us as far as this plan (does work camping usually involve nurses/medical staff?).

Before we make the big investment, I want to make sure this will work out for us both, so I thought maybe for starters we could secure a rental RV in the Tampa area or further south for the month of Feb next year and give it a shot. Are there RV resorts that have nice class-A type rental units? Or homeowners who rent, a-la vacation rental homes on sites like vrbo.com? Anywhere else I should post this question?

Thanks for any help.
