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 ...

We had that same problem while in Florida. 30 amp service, 13.5k BTU AC. When the temp got into the upper 80's, the AC would trip the breaker, off would go the power. On a daily basis! Finally It was recommended that we switch the WH and frig to propane, we did and that solved the problem. When the temps moderated, I was able to put the appliances back,on electric. (Our next RV will have 50 amp)
