Maybe so, I don't really know what it takes to upgrade to 50 amps. My brother did it on a 36 foot park model he bought with one air, 30 amps and it would not cool very well.
I have a 42 foot toy hauler with 2 but not cooling the garage area with them so coolin about 28 - 30 feet with 2 and above 90 can be a chalange but I like it cool. I do have a 12 foot ceiling in the maon area and a loft bed.
It originally only had one and the other was added in the upper bedroom. It does have a 50 amp service and most likey came with it. I have an access door to the garage from the side that a window unit fits in perfect so I am really running 3 AC units. A 15000, a 13500 and a 10000 window unit.
