Front A/C trips breaker when on hi

Hi everyone,

Been full timing in our 2024 3231CK since January. Haven't run the front AC unit much at all as its been pretty cold. Just started using it a little bit more consistently this past week and whenever we put it on hi it trips the breaker, sometimes within 60 seconds, sometimes in 10-30 minutes.

It seems to be willing to run on low consistently, blowing cold air.

I have found that having it on auto vs manual does not make a difference. Running it while the bedroom AC is on or off doesn't make a difference.

We are not running much else, just a couple of computers and internet equipment at the moment so we aren't drawing much power elsewhere. We are on 50amp shore power here at the RV park. Power to the pole on the progressive surge protector shows L1, 122, 1a, L2 123, 10-12a.

I did read through a few similar threads and wondering where to start, simplest to hardest.

I am very handy, but don't know a lot about electrical - happy to learn and I know the basics of working with electrical safely. I guess it's time to get a voltmeter.

Thanks in advance for tips!
