Adding a 3rd AC Unit
I have 2 AC's on my RV currently and I spend a lot of time in the Southwest where it can get to 110 120. 2 AC's won't cut it so I have decided to add a 3rd unit.
I welcome your experience and comments on my plan.
I will mount the 3rd unit where my kitchen vent is located.
Run a wire to my current thermostat for control
Run AC power from the unit to the rear of my RV, in the closet area where my washing machine used to be. I will add a breaker in line, and connect to the 120v outlet in the closet.
I will also run another AC line from that closet out to my electrical bay, so I can connect the 3rd unit directly to a 30 Amp shore power seperate from the rest of the RV, which would be connected to the 50 amp service.
I hope to accomplish the following:
When going down the road with the genny on I can run both front AC units and the 3rd will be plugged into the washer circuit.
When parked I can run all 3 units with the 3rd unit plugged into 30 amp at the pedestal and the rest of the RV to the 50 amp. This way I won't overload the RV's electrical system.
In the end I will have 3 15000 BTU Dometic units that I can run off shore power, and 2 15,000 btu units i cn run off genny power (7500 w Onan).
Have I thought of everything ?
