That can be from too much load at the A/C and a hard start kit can resolve that. Or it can be from too many other AC uses on. Turn the fridge on LP mode and also the water heater. Hot days make this even worse. I would get a small digital multimeter and check the output AC voltage of the generator and be sure that it is adequate. You should see at least 117 at one of the outlets in the coach. It will drop as the A/C attempts to start and if that is too low, the amperage in the circuit spikes and trips the breaker. A small meter is about $20 and easy to use. I can direct you futher here if needed on more testing. If you get me the make and model of your A/C I can get you a part number for the hard start kit. All follow ups are included in our fee. No time limit.
