We are looking at a 30ft class C that only has a 13.5 BTU AC unit installed with 30 amps power cord. We are concerned that this set up will not be sufficient to get through these sweltering summe...
They sell it at Lowes, Home Depot etc. Kind of a shiny quarter inch thick product with air pockets. It is very effective. But still recommend just getting the two AC which is right for your situation and then you won't have to deal with all that. It will just work.
