While not a direct answer, my 3 slide (2 living room, 1 bedroom) 4 A/C unit coach has computer fan vents built into the cosmetic ceiling of the front living room slides. When the slides are in, they’re in the right position to circulate the front A/C units output.

I can post pictures if desired. I’m still sorting my A/C’s out, but the extra fans seem to really help.
