I can only run both my air conditioners on SOME 30A circuits.
I am thinking of getting a portable AC but I would run a heavy extension cord to an extra receptacle - not through the RV panel. Of course, her husband's shop might not have another circuit available.
My 5er is 42' and it needs THREE ACs.
I was going to say that very very very few 40 foot 5th wheels come with a single AC. Even two 15K btu AC units is tough with that large of a 5th wheel.
I have a 35.5 foot (floorplan) 5th wheel with a 15K btu and 13.5K btu AC and if I don't start them early (before the inside temp hits 70F) they will really struggle in 90F temps. I'm thinking about upgrading the 13.5K btu AC to a 15k btu.

a lot do, depends where you live. in the northwest and Canada almost all 40 and 42 foot 5th wheels have 1 ac and are prewired for a second. yes you can get them with two, but those are special ones from the factory or the dealership ordered it with two. a second or third ac is an addon and a "money maker" so usually they are not in the base. my 5th is 42 feet long (overall) and has 1 ac prewired for a second, no way to add a 3rd unless you fish new wires through the walls and celling. it was a 89K 5th wheel.
