As already posted in your other thread...

I have three A/C units, I can run all three at the same time. You should be able to run both of yours I would have to think without issue. Really, one would not cool that coach enough in the summer. I also have one thermo, but it runs all three. You set them in the thermo itself using the buttons to cycle though the settings for each unit and heater based on the mode you are in.
