If I recall, on my PC when plugged into 30amp the second a/c is not receiving current thu the panel, so it can’t be turned on.
Depends on how the manufacturer wires the RV. That is not a generally safe assumption to make. A lot, if not most, manufacturers merely put them on separate legs of the breaker panel. Since both legs get power with the 30 to 50 adapter, it is entirely possible that both ACs could be turned on. The manufacturer would have to put in something to detect that it was only 30 amp power, and disable the second AC.
