Get the hottest air out first, provide cooler air to the A/C to further cool, and reduce any inside pressure by allowing a good exhaust while you replace that air with ever cooler air.
Not sure of the mystery here :h - this is exactly the same approach with any vehicles I've ever owned. Hot summer day, vehicle has been sitting cooking in the sun, first thing I do after starting is roll down all the windows, fire up the A/C, and allow it to force hot air out before replacing it with cold air. Much more efficient than leaving all that hot air trapped in the vehicle and trying to slowly replace it with cold air. We don't use A/C in the camper often but when we do it's exactly the same procedure. :)
