A/C can only run by itself, anything else trips it

We are now in Southern Texas and it's already a 100 degrees. Fifth wheel 33 ft with one middle a/c unit and 30 amp. I am packed in shade. It's not keeping very cool except in middle near it though ...

If your air conditioner is tripping the branch 20 amp breaker then it could be low voltage but I speculate the compressor is getting to end of life. How old is it?

The campground maintenance guy might have a voltmeter and the basic know-how to get a reading.
