Do you find you have prepping problems specific to our climate? I've never seen a home in FL with a root cellar or other 'cool' area for food storage. Maybe in the panhandle, but not the peninsula. Even basements are far more rare than in northern areas.
I really struggle with long term food storage in the event there is no electricity with the year around heat & humidity factor.
I have the same problem, as I live in south florida.
Maybe you can get a kerosene refrigerator.
They are used on RV's and in solar homes. They not only run on kerosene, but you can use vegetable oil, diesel fuel, etc..
This kind of refrigerator was invented by none other than Albert Einstein and his student Leo Szilard.
You can get them second hand on Craig's List. They are mechanically simple, have no electrical circuits, and are very reliable.
You can fix them yourself with a minimun of tools. Look up dometic refrigerator. Kerosene and diesel fuel last a lot longer in storage than gasoline. If you use a diesel car or truck, a kerosene refrigerator, and a diesel backup generator (a slow speed Lister model), you could be set up for everything.
Biodiesel would even be relatively non toxic if it leaked, but biodesel doesn't store well. Most biodesel goes bad within two months in a hot climate. Regular diesel, however, can last more than five years if it's treated with sta-bil, antibacterial stuff, and algicides.
