Drawing air from the outside? How does that work when there is a constant exhaust pressure out of the hose to the outside? THese units have a SINGLE hose, not TWO hoses. I am aware of TWO hose units for which one is input and one is output, but my ACs are both single hose.
The air has to come from some place to replace the air that is exhausted outside. It's pulling cool air out of your RV to go through the portables. Where do you think the air is coming from ? On a two hose unit it's pulling hot air from the outside and exhausting hotter air to the outside. You are not pulling the cool air out of your RV.
