your main area AC sounds like it is set to a dump position to rapidly cool off the main area, then you should close the vent a bit and duct to the rest of the RV.

This, and also thermostat location is usually in a spot to benefit all rooms in trailer. Also the vents should be located and able to rotate to best advantage. I have a round ceiling vent just outside my bathroom door, that can rotate as needed, for bathroom, shower stall, or bedroom.
