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 ...

Good advice so far. What size AC?

Check Voltage with AC running. I suspect it is your 30 amp main tripping in the trailer. Put the water heater (at least) to propane. Breaker could be weak.
