Welcome to the forum.
I'm guessing you have a 30A rig?
Which breaker?
The pedistal breaker?
If so you may be over powering your circuit.
A 30A circuit should run 1 AC and some other appliances.
It is possible to run 2 ACs but they will need to have a "SoftStartRV" installed in them.
A window AC?
Is this an add on with a separate power cord?
If so, maybe try plugging it into an extension cord and running it from a different internal breaker. There could be other things on that breaker that is NOT labeled. I have a 2019 and I have had to re-lable several of my breakers because more devices are connected than what they listed from the factory.
OR, run the extension cord to the pedistal directly,
JUST FOR TESTING.
Do not leave it plugged into the pedistal, that is against electrical code. I Don't know why, I have just read that on other sites.
