Is it bad that I could hear that last post like a story teller in my head. Great advice really. You are not your parents.
Travelling to/visiting and living somewhere are two different new things. I think looking at work opportunity in Florida works. Visiting your family prior to consider living with them might be wise (would they let you park the RV on their front lawn?) Savings are important. Are you and the gf already self supporting or do you still live at home?
A plan may involve getting a job for the next year and a half and putting some savings down.
Studying vs. Working are different lives. See how well you manage in MI. Maybe like some suggested do some short travel breaks maybe even job interviews and look at cost of LIVING regarding apartments. Visit just you then you and gf then you and the dog and the gf to the family in FL. Write down pros and cons.
It may be romantic and not work or it could seem doable.
Maybe you can move nearby for a bit so you transition into it. Try the RV life in MI. What is the closest Big town to where you are now?
You may also want to look into health care and colleges and universities in FL as that may be another way to move but still have a structure.
