There was a recent thread about adding a 2nd A/C, but I can't find it. He installed it in the rear vent cutout. Wiring may have been wiremold but to a side wall and fished down, 10/2. It terminated into it's own pedestal cord. I recall discussion about using a 50a WYE to 2x 30a plugs. Good luck finding it. I'm looking forward to your progress.
I'm wearing trifocals now but my hindsight is 20/20.
