AC

Ok I went down and bought an RV digital volt meter. With both ac units on, the refer on electric plus laptop and phone plugged in volt meter says 118v. So a 30 amp coach with an electronic controller for ac can run both ac's at once.

Yes but in a CG periodically check the voltmeter. CG power can fluctuate.

You can keep on doing it, but even though they are small units, you are riding on a tight rope and eventually what is going to happen is you are going to burn up a motor on the AC. And you can tell when you are in a RV park and the shore power is lower then what it should be, the motors on the AC start dragging and eventually if you keep running it, it will ruin your electric motor.
But I have seen some of those small units running on 30 amps.

The Coleman draws 14.9 amps. So both on will be right on the line for thirty amps.

That depends on which AC units are there and whether it is set up so one has priority. On some 30 amp coaches there is a control that will not let both start at the same time, but both can run, with the second one starting after a time delay.
The coach builder should have that information if its not in the owners manual.

Ditto. Get a plugin digital monitor . If volts drop below 108, watch it closely. If volts drop to 104 or below, turn something (110) off. If you do not, you will incur heat damage. Heat damage does not seem bad immediately but is accumulative and will shorten the life of major appliances, like your AC. Some say it will run fine, but may be ignoring or unaware of the long term damage that shortens the life.

My coach is 30 amp. I have the Intellitec Electronic Climate Controller. The guys that do the work I can't have told me to just set the units where I want them and turn them both on. I just changed front a/c to 15k and he said just let the Controller take care of it.

I have no problem running 2 units on a 30 amp circuit. My EMS shows around 22 amps, sometimes a little higher, but never over 26. The EMS won't allow both units to start at the same time. My units are only 13,500 btu heat pumps.

Figure each AC unit at 13 Amp or so running.

In theory yes, but you have to turn most everything else off, even the ice maker and run the refer on propane.

My 2005 bounder has a 50 amp service. But when camping @ a 30 amp is what I was wondering about? I can turn one off and then turn the other one on after it starts.
