30A Circuit Breaker at house tripping
Motorhome plugged in full time. Temps outside around 100-105 degrees. MH basement a/c running constantly during the day. Except when the circuit breaker trips :( I'm talking about the one on the side...

I sure appreciate all the knowledge you all are sharing. What an education for me. I am not a DIYer electrician so I won't be doing some of the stuff that has been suggested myself.
I stayed home today checking the situation throughout the day. According to my Progessive Ind. EMS, the voltage IS DROPPING! Started at 119 with nothing on. Then with frig on and a/c running, compressor #1 only...voltage shows 114, amps about 15. Later in the day, hotter outside, compressor #2 kicks on...voltage shows 108, amps about 26-28.
Shortly thereafter, circuit breaker trips.
This has not happened in past summers at the house. I was thinking...I just had a new house air conditioner installed about a month ago. Replaced a 40 year old unit. Perhaps related to the voltage problem? Or is the voltage a function of motorhome wiring, clean connections, etc?
As noted, I am not knowledgeable in electricity. I understand that it is the motorhome appliances that produce the amp number, but where does the voltage number come from?
I may change the breaker to see if that helps. For now, I am doing what GPWayne suggested....Turned my Power Mgmt System inside the motorhome to 20AMP, so it will automatically prohibit the 2nd compressor from running. Even with that, the voltage went down to 110 with frig on and a/c running. Went to 116 after a/c hit set point and shut off.
KD4UPL...The breaker panel is on a hot side of the house. All the breakers feel hot to touch, the RV one no more than the others.
Again, thanks to everyone for your kindness, time and effort in helping me think this through.
