So I have a 2020 Heartland RW 414 with the optional 3rd ac for the garage and have a problem tripping the breaker when the garage ac is running with any other ac middle or front/master. When boon docking and running on the generator I can run both the middle and front/master AC and not trip the breaker on generator. When running the rear AC on it's own will not trip the breaker either and does work fine. I have tried multiple combinations running the garage AC with middle unit or garage with master unit and either of those combinations trips the breaker. Please note I am not trying to running all three ac at once, nor am I running the fridge, microwave, or water heater. I have taken this to my dealer and to be honest with you I don't think my dealer knows **** and if they are correct this should be addressed from the factory to resolve it. Dealer told me you can't run two A/C's at once which is total BS, like I said I can running both middle and front ac with no issues. I don't think I need to say this, but I'm sure I will be asked it is an ONAN 5500 generator. To note as well it is not tripping the 50am breaker inside the trailer it trips the breaker on the generator.
