Not accounting for startup surge, even with easy start capacitor.

So with one AC using 8 amps running off the batteries or a 15 amp plugin, that would leave 7 amps to spare - right?

In mine the 12 volt battery runs only the thermostat. The compressors draw power from the AC line. I suppose if you had a BIG battery pack and inverter, you could run the AC's off 12 volts. No practical way to do it though.

Probably not. In theory as long as that was all you were running, yes. In practice you have other things like the converter running to supply 12 VDC to charge the batteries and supply whatever 12 V systems are running. Thus you have 7 amps of spare from the air conditioner but some fraction is already accounted for so you cannot plug in a 7 amp load.

My 1995bounder has a switch to let you select which ac you run when plugged into 30 amp. My generator will run both. Haven't tried 15 amp yet.
