Onan 7500 Watt Generator
We have an Onan 7500 watt generator that we run while driving to keep the AC's running and keep the coach cool. Lately, every time we run the AC's using the Generator the 35A circuit breaker on the g...

The inverter could draw a lot of amps depending upon what is on. Turn it off and consider turning off other CBs except perhaps the refer.
Also depending upon the AC size they draw a lot of amps up to 15.5A. So I'd guess:
1. Startup surge current is the cause.
2. ACs can start to use more startup current if they have a hard start capacitor and it's going south. This sounds like your case.
3. Or if not equipped with the hard start kit consider adding them.
4. It could be related to the age on the ACs.
5. It could also be loose or coroded wire connections.
