There are reports of running a 13500 btu AC with a Honda 2k unit with the eco switch turned off, but those reports do not record the voltage when the roof air is operating.
Perhaps this will help - here's a video I made a few years ago powering my Coleman Mach 3+ 13,500 BTU A/C with my EU2000i. A/C was equipped with an SPP6 hard start cap, I wired the thermostat with a Fan HI / Fan LO switch with a centre off position so I could start the A/C compressor only, then manually start the fan a few seconds later once the compressor came up to speed. As you can see voltage drop under full load of the A/C compressor and fan was about 4 volts.
