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 ...

Wiz, It was actually his 30A CB as later clarified.

OP, That's good voltage, so it appears that either you're using over 30A or have a weak breaker.
