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 ...

Sounds like a low voltage issue. When voltage sags, amperage increases and can trip breakers and worse, damage your a/c over time.

Are you in a park with many other rigs running a/c? That's a common cause. Check your voltage when running the a/c.. if possible. If it's below 112 I'd find another park.

Solar panels are not going to help.
