Running one air conditioner off the generator and the other off shore power is not a practical solution... Even if it were possible, if you are in a campground hooked to shore power running a generator would not be permitted...
Depending on the size of the air conditioners many people report that they are running two off 30 amp service...
I could not find the post by "chaffeekid" you referred to
You can help us help you...
Please state make model year of your motorhome and make, model and size of generator.. Do you have a power managment system in your coach?
