I'm confused about what I need to do to run the A/C in the coach. I 'think' they said the generator has to be on, but what if you are plugged into electricity do you still have to run the generator.
Right now it is too hot to even do anything so my new toy is just sitting in the drive way taunting me. But at 110 heat index I'm staying inside! Hope the promised rain comes tomorrow!!

If you're plugged into electric, you can run the ac. Otherwise you can't use it unless the generator is on. This is for YOUR setup. There are people out there who have a big enough inverter and solar to actually run ac. Not many, but some.

Just a thought: when you all are saying she can run the AC if "connected to electricity", I'm not sure if she's thinking house current or CG 30 amp.

I have been able to run my AC off of house current....but I am careful to run it off a circuit that doesn't have other things pulling off it and don't have other things running inside. It is no different that the room AC that I stick in the window of my office and plug in the wall socket. But then mine is a small rig.....

Ah, see, you are smart. I didn't and tripped my breaker and I think that is when I blew some fuses in the rig.

Glad to know if I'm on electric I can run the A/C but do need to have the batteries on at a campground. And even if you use the 15 adapter to plug into the house it can cause problems. I'm safe as to try I would have to have a new outlet as the our outside plugs are only for two prong....

BJ, I had a 30 amp service installed at the house just for the motorhome, just like the outlet you would plug into at a campground. It has its own dedicated service and I am able to run the A/C with it. But don't try to use the A/C & microwave at the same time.

Long before anyone told me not to do that, I did. I must have an unusual rig, as it has never blown a fuse for me. I know it does for some. But every rig is different. Something else to be wary of is running a hair dryer with any other major appliance. And if you use electric heaters - look at what they pull. I learned last year I could run two - they were off different circuits.

my ac in the fifthwheel has its own dedicated circuit.

I guess the dealer either misunderstood my question or didn't know what he was talking about because I just went back over my notes and when I called to tell him about my a/c problem I asked him and wrote down his answer which was that the gen has to be on for the rear air and to be sure I turned off everything before starting the generator. The answer just didn't sound right or logical to me sure glad I asked you all.
