With no state income tax, Florida doesn't really care. They'll still probably get you for registration and a few misc fees but it's not something they pursue. Lots of people use Florida mail forwarding services as an address with no issues.
The issue is does your former domicile agree that you have moved:
If California is looking at a $30,000 income tax bill and you have no links to Florida other than a $5,000 piece of swamp land, there is a good chance will tell you to pay up and it's guilty until proven innocent. Doubly so if you actually spend several months of the year in California.
If this is a lot in an RV park, you have receipts, your drivers license is Florida, Florida utility bills, Florida phone, Florida doctors and other documentation that you spent a large percentage of the year in Florida with minimal time in California...California will likely back down.
Unfortunately, there isn't a simple do X, Y & Z and you have indisputably changed your domicile. It's more a preponderance of the evidence. For regular folks who sell the house in the old state, buy a house in the new state and everything in their lives transfers to the new state, it's so overwhelming that it's not an issue and usually, the old state won't pursue it. For full time RV'ers who may spend a minimal amount of time in the new state and may return for extended periods to the old state, it can get sketchy and high tax states have a tendency to take a guilty until proven innocent stance, so you want to make sure it's clear cut that you moved and can provide supporting documetation.
