Have you considered upgrading to a 50A service? Then you could run all 3 ACs and the MW, HW and hair dryer all at the same time. Of course you would need a 50A site.
There are various ways to accomplish this.
Another option is a 50A to 2 30A plugs, one for the current plug and the second one for everything the daughter needs.
I believe he has 50 amp on the trailer. He was adding a 20 or 30amp separate circuit for the 3rd A/C separate from the trailer electrical.
You do bring up an interesting point. From my understanding, 50amp service is actually rated at 240v, so at 120v, it is rated at 100amps. If this is the case, why do 50amp trailers need load management devices to handle 45 amps (3 15k) of A/C units? This should be less than half of total capacity.
