Yeah, if I have ALL the vents open, the airflow say at the very back where the bedroom vents are will be weaker. But if you're in the very back, maybe in bed getting sweaty (lol. tmi.), you can close off every single vent except for the two over the back bed and have tons of airflow where you need it. In my opinion, adding extra vents to the system or the ceiling panel is a mod with really no downsides. These roof AC's don't run super cold evap temps, and increasing evap airflow doesn't effect the evap temps that drastically. That means you need a ton of air exchange in the entire coach to cool it down since the temp drop is so little (15-20 degrees lower than intake temps). If the output temps were 40 degrees below intake temps, it wouldn't take that much airflow to cool things down. That's not how these systems work.

Where did you tap in to power fans?
