IMO there should be nothing about the starting current or voltage that should trip the GFCI. I think something is flaky somewhere in the generators, air conditioner, GFCI, or the wiring.
I agree. The GFCI works by monitoring the common mode current on the neutral and hot. Ideally, it should only react to the powerline frequency currents, but most don't filter out other frequencies very well, and it could be that some sort of higher frequency noise could cause it to trip. I suspect it might be the inverter output being noisy during the period of inrush current to the AC, but the only way to tell would be to put an o'scope on it.
The first thing I would try is to replace the GFCI outlet with another brand. You might find one brand is less susceptible than another.
Not to get too far off topic, but has anyone seen any arc-fault breakers in campers yet?
