My Torque Toyhauler came pre-wired (20A Romex on separate breaker) for a second AC in the bedroom. That's great but with four daughters and their friends who stay in the back and West Texas summer time highs over 100 degrees my real need for an additional AC was in the garage of the toyhauler.
Pulling Romex from the breaker panel in the front to the vent opening in the back was going to be too much trouble and involve tearing up the walls and ceiling.
My solution was to buy a Hi Efficiency Dometic that just draws 8 amps and run 20A Romex to a Marineco 20A inlet mounted to the exterior.
When I'm in a campground I run an 12AWG extension cord from the inlet directly to the power supply and when I'm dry camping I run the extension cord up to the exterior 15A outlet and run it off the generator. With the Hi Efficiency AC drawing around 10 amps (8 amps cooling + 2 amps for the fan) I haven't had any problems with it blowing the 15 amp breaker.
I haven't decided weather or not to go with a third AC in the bedroom, it's kinda warm in the day but at night the main AC vents cool down just fine. If I don't mount a AC in the bedroom I will run 20A Romex from the 20 amp breaker for the bedroom AC through the basement to an exterior 20 amp outlet and get the garage AC off the 15 amp house circuit when I'm running the generator.
This setup works great, but now I'm gonna sit back see if all the engineers will tell me what I did wrong?
