Last time I looked at specs for 9,200 unit it wasn't a Power Saver, and was rated to use more power, hence no real advantage from an electrical standpoint. From a thermal/cooling standpoint it may make sense so it doesn't short-cycle as often at night when installed in "tiny" RV bedroom. Personally, I'd go with the 11,000 PS if it pulls less power.
By the way, I saw reference in Onan generator specs to a "7,800 BTU/hr high efficiency A/C (5.5 Amps or less)" but haven't been able to find information on it. Something like that size, if roof mounted RV type, would be ideal to supplement a single-A/C motorhome that needs a little more capacity. That small an A/C unit should run on a 30-Amp service or 4,000-watt generator.
I'm just wondering if Onan picked a 7,800 BTU/hr high efficiency A/C out of thin air as a hypothetical example, or if they actually know of one that exist?
