Again, thank you everyone for the feedback. I ended up calling LazyDays in Tampa and talking to their registration department. Sharing the information here for the benefit of future readers.
To register a vehicle or RV in Florida you need an address and an ID. That ID can be your local driver's license or a passport. The dealership (LazyDays in this case) can take care of registering the RV for you. They will give you temporary tags to drive off the lot with and will send you the papers and plates to your address later on.
Using a mail forwarding service we can then get those FedExed to us wherever we are in the US.
So, Florida it is for us. And more specifically, Tampa, as suggested here. I now have TONS of questions about choosing the right rig for our needs, but I'll start a new thread to keep everything neat and tidy.
