Our previous coach had 2 A/C units and 50 amp service. When connected to a 30 amp outlet, there was only enough power to run one A/C. You need to watch what else is drawing power, water heater, microwave, fans, hair dryer or toaster.
If you are plugged into 50 amp, and not running too much else, you should have enough capacity to run both units. A previous thread discussed the power draw from each of these.
