Thanks for the advice! I was able to achieve it and wanted to share;
Indiana will let you title and register you vehicle in you are a non-resident but you will need the following: a birth certificate, social security card, license from your state, and 2 proofs of address in your state, as well as proof of insurance (only glanced at). With that I was able to get plates & registration for 2 years, and they agreed to mail it to the campground I am staying at.
I did mail back my plate and transfer of title from my old car that I traded for the bus. Apparently FL has a 30 day period you get to return these things, or else they suspend your license
From my research it looks like when I'm out and about I will go to Montana to get a lifetime plate to never worry about it.
