Chief, mine originally had 1 ducted 13.5 Coleman Mach 3 mounted about 2/3 back from front on roof. 8 ft in front of it was some kind of supper vent fan over the kitchen. We seldom cook inside. We took the fan out, installed another 13.5 Coleman mach3, ran wiring in a similar colored conduit across the ceiling, down the wall, thru floor into a storage bay where we located a 30 amp breaker. Then ran it out of box to a newly added 30 amp plug. Depending on the service at the campsite, the coach is plugged into 50 a (using a dog one adaptor) or the 30 A. The 2nd non ducted unit gets plugged into either the 30 a or the 20 a (using another adaptor). Using 20a the plug doesn’t get hot and I can actually cool the entire unit better with only the 1 non ducted AC.
