My 2017 Fuzion 417 came with 3 air conditioners. You can only run 2 at a time. Further more you must run the middle unit and choose from the front or rear unit to help cool. There are only 2 breakers for the air conditioners. I want to run the front and rear air conditioners OR run all three. My question is how or where are they controlled? I know the thermostat tells what to run and when, but is there a way to run all three? I can 2 of them on a 30 amp hook up, so why am I not able to run all 3 on 50 amp? I understand I am going "on my own" here and keystone did what they did for a reason. Has anyone been able to run 3 ac's at a time?
