No doubt one would be willing to pay $800 for a new unit to replace the 15k that may otherwise be just fine. However if you buy the Power Saver 48208c969 Mach 3 Power Saver, 13.5K BTU/h A/C, Black it drops to 10 amps which is very efficient compared to 15k. Main advantage here is that you would not have to worry about anything with the 30amp or 4KW generator as you can run your whole coach off generator. Beyond the money, you lose 30k BTU to downgrade to 24.5k BTU. But is option and would be my preference money notwithstanding.
As far what you are doing today, I like and it is close to what I would try but with one subtle change if I followed your post fully. Maybe I should ask the question before assuming? In your current config, can you shut down all of the other main amps sources and run both AC's off Generator; and optionally run the rear AC off the generator without running the front AC?
If so; that is what I seek because I don't think I would need both much; but if I needed, I could; or if front AC unit went out, I could still run the back unit off generator when not connected to shore.
I was thinking of have the 2nd unit's 110 plug in a place in where I could plug it into the incoming shore power for 20 amps service, or plug it into existing or newly created 110 receptacle that connects to main coach source of 30 amp power. Because of the unplugging required; no chance of backflow electrical energy.
Thoughts... because I have never encountered this issue with my tents
