Otherwise the GFI trips in the bathroom or the breaker at the pole (camping) Shouldn't I be able to keep both a.c. units on at all times even if I want to make a cup of coffee? This has happened at the last 3 campsites. I took it in for service and they say nothing is wrong.

Now the OP said he has had the issue at multiple sites so the chances of him having bad power at all of the sites is slim. Possible... but unlikely.
I have a hardwired Progressive EMS so I always know the voltage and current of my 50A service but apparently the OP is not using an EMS so I think it is still worth him checking for poor connections given the issue has happened at a few different sites.
There have been enough reports and pictures of shoddy wiring on this forum that it would not be a surprise if he also has a poor wiring connection somewhere. Poor connections can lead to an over-current situation if the full gauge of the intended wiring is not making proper contact. A poor connection from improperly installed wire nuts would be like using a 12AWG wire when the service really called for 6AWG. That could cause a breaker to trip and it could also cause heat with melting or even fire in extreme cases.

Read the OP again. The complaint was NOT that he couldn't run both A/Cs at the same time. The complaint was that he couldn't run both A/Cs AND another major current drawing item such as a coffee maker or microwave. The answer is: a 30 amp coach cannot run 3 major current appliances at the same time as I explained in post #3.
There is no problem with his coach; like all 30 amp coaches you have to power manage.
