Seasonal - is only a term used in cold winter climates. Not sure what residents in Florida or other warm weather winter climates consider seasonal since they can camp 12 months a year.
Saying that, 90% of the county has cold winters.
Full Timers do have a unique set of issues plus all the issues that seasonal RV'ers have.
I break down RV'ers in 3 categories.
1. Full Timers - live 100% of the time in RV's
2. Snow Birds - live in their RV for a few months per year during winter months.
3. Campers - do not consider that they are living in their RV. They are on vacation or enjoying a weekend. They are using the 'R' in their RV.
Then when you break down the RV being used...yikes.
