That is probably the biggest compromise I see; although it too has pros and cons.

On my "older" Class C we typically turned off the A/C while we ran the microwave for a few minutes off the generator. The 4,000-watt Onan just struggled too much with older lower-efficiency units. On rented Class Cs we often do the same.

I agree that if you were running two A/Cs with a combined load of 19 to 21 Amps, it would be necessary to turn one of them off for a few minutes to run a microwave, coffee maker, or hair dryer, but on the bright side one of the two smaller more efficient A/C could remain operational, which beats no A/C at all.
