Check with Auto Owners Insurance. They do write policies in Florida and their price was 1/3 of Progressive for our coach with agreed upon replacement value.

My insurance for my coach is less than $400/YEAR total for my coach, including $5000 coverage for personal items inside the coach. Here is the link to their website:
