Dometic does have a multi-zone system that you can use with a comfort control center II thermostat. But it's quite a bit more money to go this way. And really I prefer to manage the two manually.
For instance right now I've got the TV on but it's hard to hear because the AC is running. It's fairly cool outside now so one AC unit can take care of it. So in a situation like this I might run only the back unit and not the front.
Not too much worry about running both and making it too cold and causing an icing problem. The Dometic Brisk Air's have icing sensors on the air intake fins. That should shut down the compressor in the event that you accidentally left both units blasting and left or something. But so long as you always set the thermostat to a reasonable temperature that should never matter anyway.
Like I tell my daughter, it doesn't get cool any faster when you shove the thermostat down to 50 degrees.
