If it was truly 30amp surge wouldn't that trip my 15amp breaker?

That a/c is 10.5 amps at 120 volts. 1260 watts + 10% overhead and some power factor puts you right at the inverter max. Batteries are providing 120 amps and you need 4+ to get any reasonable run time.
BTW what size and length is the 12v wire? 5' of 2/0 would be about my minimum rating.

No. You'll need at LEAST 4 batteries to handle any a/c load, and even then it will be for maybe 15 minutes max.
The startup amps for the compressor are possibly in the 30amp range, meaning 300a from the batteries. That's what your two batteries can't handle.
