A few years ago Coleman advertised how their 13,500 BTUH A/C reduced current from 15.3 to 11.2 Amps, and now they have specs showing 10 Amps. That 10 Amps is 1,075 Watts, which represents an EER of 12.5. There’s definitely room to make that EER much higher and thus reduce electrical requirements below 10 Amps.
Even at 10 Amps, two units for a total of 20 Amps is quite below 30A service.
P.S. — I’m a little skeptical about 10A rating and would want to see/measure myself, but even if close, it’s pretty good.

My 1500 watt units draw 12 amps on high typically
Maybe an amp difference between the three at 120v per line
You can watch the amps climb when a camp ground has a high load
