Harold, here is a "thinking out of the box" way to easily get to Florida, assuming you are traveling there within a few days as opposed to a month to get there.
1. Before you leave home, add a couple of gallons of water to each of your holding tanks. Then, add some RV Antifreeze to those tanks. (This assumes they are in a "unheated bay" but I find that unlikely)
2. Shut off your fresh water pump (I assume you have it winterized since you are in Ohio already).
3. Buy about 6 gallons of drinking water in one gallon jugs. Put one in the bathroom and one by the kitchen sink. Sit on the floor during transit.
4. Use that until you get to where it warms up.
This may sound funny but just last week one hour after I left my home in Nebraska, my water pump ceased running. I decided on this approach to keep moving. I bought the water at a local Wal-Mart as I went buy. I used those jugs of water for everything without any problems. If you need more water, it is easy to get. It is still pretty cold where I am at and I am still using that process until I replace the pump in a couple of days.
Just pretend that you are camping in "one heck of a nice tent" as you travel and enjoy the cold.
