Running the fan on high can be counter-intuitive since the compressor shuts off during the satisfaction of the T-stat and the fan continues to run and bring in the hot/humid outside air which then causes the dehumidifier to run which produces heat... so on and so on.
Well, if your A/C is like a 1970s model. It might have a Fresh air intake, but modern ones do not. The outside and inside air flows are 100% separated. It does not draw outside air into the RV unless there is a defect as the two sides are sealed from each other. Outside air is ued ONLY to cool the condenser. It's not brought in..
Same with most window A/C's.. back in the 80's they had "Fresh air" doors (and/or exhaust doors) you could open.... Today they do not.
For the very reason you cite in fact.
I've been on the roof and taken the cover off multiple makes of A/C's and there is only a very tiny path (The Drip Tray) that's common to both sides and it's usually water locked if the unit has run for any period of time.
