Deceiving I KNOW!
I had a "local" generator guru "rewire" my generator and install a RV 30 amp outlet.
OP I could be wrong but 20 amp may be the most you'll get out of this generator.
The a/c can draw up to 18 amps to start "higher if super hot out" and will run in the 12 -14 amp range.
After reading your mention of this in another thread a couple of years ago when you first did this, I started to think about it, and decided it was the right solution for what I needed. So....
I recently did the same to my gen-set. It was easy, and was done for the price of the RV receptacle, some wire, solder, and a thirty-amp breaker. I followed the suggestions here:

Fortunately, Coleman brought out the two stator windings with two wires each, not just a single one for the center-tap neutral. That allowed me to parallel-wire the two windings for full power availability at 120 volts, but eliminated the ability for the gen-set to produce 240 volts at all. I never have that need, so it was moot.
Though I have only one roof-top A/C, I suspect this would now run two (if they didn't both "start" at exactly the same time). It will run the A/C and the microwave simultaneously.
The down-side? It's an open-frame gen-set, and it's noisy. I built a "doghouse" surround for it, complete with air circulation blower, but I only set it up if we're going to be in one spot for a while.
