Doc, Your conclusions are correct. Some room A/C window units have a little passage that can be opened to bring in some outside air. We had an old Coleman Mach RV A/C that I thought had something like that, but it's been a long time so don't hold me to it. Our newer Mach does NOT.
BTW, that diagram is what you need to understand to periodically clean your Roof A/C. It's pictured without the plastic shroud. The angled shrouding over the Blue Part (evaporator) has to come off in order to clean the blue coil, and the drain pan and drain outlets directly under the blue coil. The red coil (condenser) may trap a few leaves but that's usually it. Notice, the air blows through from the front side of that coil.
What the OLD Colemans had was a lever on the inside shroud that caused a damper door inside the metal plenum to open and close to direct more air out the REAR than the FRONT. But not to allow outside air IN. The only units I saw with the Delta's were the original Winne Elandan and Itasca Windcruiser from the mid 80's. Doug
