30 amp for duel AC

I can and do run both AC's off a 30 amp service. The lake does not have 50 amp, so 100+ degree days need both to stand a chance of sleeping. I have to turn off the converter (battery charger) and run a minimum of lights, fridge on propane no microwave or electric water heater. Biggest issue is starting one ac, and letting it run a min before starting the other. Once they start cycling, it gets exciting. I do usually trip the 30 amp breaker once or twice a trip.
