It's been too many years since I used to work on little window units so I had to look up an example.... found an 8,000 btu window unit rated at 6.2A....just for a point of reference.

Thor uses 5,000 BTU/hr window-type A/Cs in rear of Class C toy haulers along with a 13,500 in front living area. Keep in mind the rear garage can also be used for sleeping, and I'm sure a 5,000 A/C is plenty to keep garage cold at night. They list this combination of 13,500 plus 5,000 A/Cs with 30-Amp service and 4,000 watt generator. Unfortunately the 5,000 looks like cheap brand which probably means it's not high efficiency.
For comparison, there are slightly-higher-cost brands of 5,000 BTU/hr A/Cs that have EER of 12.2 that only pull 410 watts, or under 4 Amps.
Also, Jayco uses 2 X 11,000 Power Savers (total 22,000 BTU/hr) on some models and run off 30 Amps and 4,000-watt generator. They do include power management though. Still, at +/- 9.5 Amps each (standard condition) they should run most of the time unless a third high load like microwave was started for a few minutes. Other than microwave, hair dryer, or coffee maker, I can't think of too many items that would force shutting one of the two A/Cs off for a few minutes -- likely the bedroom A/C.
