mpac165 rather than camp grounds in San Diego or Florida look at mobile home parks or trailer courts for your stay if you plan to plant yourself in one spot for months at a time. I pulled up a Google map of San Diego and searched for mobile home parks which reveled a lot of them. The second one I looked at had RV spaces for rent by the month for $500 a month with a $200 security deposit. Beyond the deposit that would save you some. Granted it might not be as nice as a camp ground but $800 a month verses $500 is something to consider.
(Shady Lane RV Park)One item no one has mentioned is you might need transportation once you and your new home get to your destination for simple trips such as groceries, general supplies, sightseeing or other outings. Using the coach for such is a bit of work with set up and break down plus a bunch of potential hazards anytime you are out on the road. I'm thinking a pick-up and trailer might be a better option. Many older class A's only had a 3500 pound towing capacity which can be very limiting. Also the added cost of hardware needed to tow a second vehicle and other additional expenses. Just something to consider.
Good luck.
