I googled BT Cruiser because I'm not familiar with them, although my first RV was Class B Roadtrek. The Cruiser looks more like my current 'C' than my previous 'B'. I'm impressed. Very roomy. I do have one question. If you intend to spend the winter in Florida, do you plan on moving around a lot? If you stay in just one CG, you'll need another vehicle to get around or hook/unhook utilities from the Cruiser to shop, sightsee, etc. If you intend to move around, you can do your shopping and sightseeing while you're moving.
You can always rent a car from Enterprise. They pick up and deliver, and I imagine there are locations all over Florida - usually near airports.
Sounds like an adventure!
