ive been in busses that have solar on top and are spray foamed.. so they have defacto shade over a good part of the roof and the spray foam is an obvious Mega improvement over the crappy factory insulation of esp older busses.. they stay cool with a single A/C running until it gets real hot out then a second unit runs intermittently and thigns are nice inside.. shut both units off and it starts to warm up pretty quickly.. with a fully foamed floor you'll have the best bet, otherwise the floors become a huge source of incoming heat rather quickly if its in the 80s or above outside...
in a regular house things are different.. i think about my own experience with my kitty for 15 years.. and yes the house lost power multiple times during summer time...
a typical florida home is built on a slab, slab floors will retain cool temperatures for a long time should the power fail.. a pet can easily lay on the floor and maintain body temperature.. most people have water readily available for them at all times and so they can stay cool and hydrated for hours at a time in a house wit ha power failure..
in my own house it has a basement.. so kitty could get on the kitty basket-bed I had for him in the basement (modern house clean / dry basement).. and he would stay very cool..
in winter power outages, the basement furnace set to 60 degrees on a battery backup (gas unit only pulled 700 watts when running).. would keep him more than warm enough to survive, esp in his kitty bed.. in fact typically the main house level also stayed near 60 as well..
to the OP: im not sure what kind of build out you are planning, but it needs to be pretty stout or you need to be within a few minutes of home should something happen..
you havent answered me on whether you are self-powered or have power and how many watts at your parking space.. in a stock bus during the day in florida, your A/C is going to really rack up the KwH.. even a minisplit will pull 1000-1200 watts (12,000 BTU is the biggest 110 volt unit ive seen)..
we need more details on your build to help better..
before you order a mini split you need to plan your build.. go look at them online.. Pioneer is a favorite of many here and has proven to be pretty reliable.. look at them and how you will hang the condenser unit, and where.. I cant help you there because im not underneath your bus, im not sure what your buildout looks like..
you can search the forums for mini split installs and see how others have installed / mounted and set theirs up for ideas.. my bus builds are different than many because the emphasis is on road travel for me vs being stationary..
you need to plan this move a little more.. you have a great start with a place to park and live while you build, thats a Huge advantage over many.. but plan your build, even if it means renting a room or a month to month apartment for a couple months to get rockin N rollin..
