I have a new Montana Mountaineer with a Dometic Duo Therm as well and experience something similar.
It appears that there are two options:
1. Open the vents in the unit and all the cold air will blow out of the AC as that would be the shortest path and the there is hardly any air coming out of the ducts.
2. Close the vents in the unit and it will force all the air through the ducts.
We let the air blow straight out of the unit during the day and then force it through the ducts at night to force it in the bedrooms. You could also open the vents in the unit part ways to get a combination.
I didn't figure it out immediatly either, but just look close at the unit and you can see that you can close the vents on the unit itself

your switch should be oopen but when it reaches 41 degrees it should open so the system shuts off before it damages the compresor by sludging it, i have the same unit and my compresor runs for 5 seconds and shuts off, i checked the amp draw at the compresor and it draws 21 22 amps trying to start after the initial 5 second run, but it wont come on againts a load so the comprresos equilizes and tries to start over again with out positive results. i bipass the external obverload on top of compresor terminals area, still no fix yet, the relay on the control board continious to send power to the compresor and still draws , so if there is a problem with the control relay i would open up and dont send power to the compresor so i dont think is the relay, i am a a/c service man for
35 years and do this for a living still today, by experience i think it is the compresor gone bad but will try by passing the relay just to see what happens, also it could be bad capacitor since it have a hard start relay and start capacitor (black )also a run (silver ) capacitor they check ok, there is no way to check the charge unles you install a saddle tap to check presures and rechage this unit i think the compresor replacement is the way to go ( around 250) plus labor and freon r22 e mail add firstname.lastname@example.org.
