Do you run house AC while on the road
I am contemplating the purchase of a motor home... class A or Super C. I currently pull a 31’ trailer and am looking to consolidate the living and driving into 1 vehicle, adding conveniences like auto...

Some of these rigs have big inverters, battery banks and solar... does anyone try to use an inverter to power the AC - and pull power from an alternator? And solar?
I guess anything is possible, but practical? Each AC would be 1500 watts - 15 amps running. That doesn’t seem like a big load to add to an alternator.
I’m not worried about fuel use, just hrs of generator use.
That's 15A (or a bit less) at 120V; the load on the alternator would be closer to 150A (assuming a 12V system; half that if you happen to have a 24V system). It's definitely a big load to add to most alternators. That being said, it might be practical on some rigs, at least for a single roof air conditioner. (You'd have to make sure the battery combiner/isolator circuitry and wiring is up to the job, besides just the alternator itself).
