I chose an RV for exactly the reasons you suggested... wanting to be able to travel everywhere! If you own a condo in Florida, I hope you love Florida. If you own an RV you can go to Florida until you get bored, then try Mississippi Gulf coast, then Louisiana, then South Padre Island, then Austin, then the Southwest, then California etc etc.
We have places that we love to go and return to every year, but having an RV gives us a variety. Its our beach house, our lake house, our cabin in the woods, our apartment in the city, etc. We love it, I hope we continue to love it as we get to retirement age too!
