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 ...

"Just the breaker to the A/C flips in the panel and shuts off all electric in rv."

:S
Just A/C breaker tripping would not shut down all electric in rv.
Rest of rv 110V electric should be on other circuit breakers.

That sounds more like the RV Main breaker tripping.
Overloading.....or weak breaker

Simple plug in AC Voltage monitor will help you check voltage
