I don’t know about all the above said. I do know in my two class Cs with only the engine AC working. The cab and the living space up to the kitchen area were cooled. Past that when I stopped I had to turn on the coach AC to get the bedroom cool also with the house AC. I do insulate the cab from the house when stopped.
When I had a class A I had to run the house AC on the road when driving into the sun. The chassis AC did not compare to the AC in a class C.
Just me experience with a gasser Class A.
Which is EXACTLY why I was trying to share some knowledge.
The Ford E-Series A/C is incredibly powerful, but it’s ability to blow air around is severely lacking. It has a puny little 12 volt fan that just isn’t up to the task of moving enough air to cool a M/H.
However, using the above-noted method of opening the rearmost roof vent allows the vacuum to overcome what the fan can’t, getting cool air to the back and draw out the hot air back there at the roof level.
Some people however prefer to argue instead of learn, nothing new there.
