Coleman now makes an energy efficient 11,000 BTU/hr air conditioner that draws less than 10 Amps under normal conditions. Start-up current is much lower than a standard 13,500 or 15,000 BTU/hr AC. I would guess that two of them may start on a 4K Onan (it would have to be tested). You'd have to start one AC first and base load it, then after a few minutes start the second AC. Again, it'd have to be tested. Coleman engineers would likely be the only ones who would know in advance if it's doable.
