Unless they have changed something drastically you have a duct issue.
Quite a few people have looked up into their ducts and found blockages and or major air leaks into the ceiling.
I haven't taken the time to use my remote camera to look into our ducts yet, but I have it in the camper to look when I have time.
If your out camping now and want a cool camper here is what we do most of the time. In the bunk house Open the vent on the bottom of the unit and the unit will suck in and blow out all from the bunk house ceiling. Our bunk house is usually 20+ degrees below outside temp. With 118* at lake mead this summer we had the bunk house at 73*. Make sure when setting the main thermostat, which controls the bunk room that you set the fan to high. Low fan speed can lead to frozen coils.
Keep the bunk house door open to allow the cold air to flow to the main living area. We have two small fans (maybe 8") on the rear wall shelf blowing toward the bunk house door opening.
The master bedroom AC unit thermostat is in the master and we set the fan on high and 70* and for quick cool down of master bedroom open the vent on the bottom of the unit. Then when nice and cool and depending on the outside temp we sometimes close the master bedroom unit vent and the air will trickle out of the vents in the bathroom and living area ceiling. Most times we leave the unit vent open and leave the master bedroom door open and set a fan on the floor in front of the washer/dryer doors and blow the cold air out of the room along the floor into the living area.
Airflow out of our ceiling vents is very little if we leave the AC unit vents closed like they should be and even less when the AC unit vents are open. But with AC unit vents open we are getting the cold air out of the units. We were able to get the main living area to 78* which doesn't sound great but it was 118 outside not a cloud in the sky and no trees for shade, bunkhouse was in the low 70's. In temps around 100* or less the wife and kids have blankets to wrap up in when watching tv. I like the camper cool as I can get it.
