MY BET IS AS FOLLOWS......
Speaking from experience, MY 233S the curb side roof duct for the AC is COMPLETELY OPEN behind the plastic trim piece that finishes that roof vent out in the bathroom. It's 4 screws that hold that up there, take them out and the plastic trim square that dresses your ceiling into the vent opening will slide right out. When you do this, styrofoam will snow down onto you like crazy (this is normal from poor cleanup at factory) so wear safety glasses. With that trim piece out, look at the profile of the roof and forward, you will see styrofoam sandwiched between thin plywood and a NICE OPEN DUCT that ice cold AC air is blowing straight out of! This AC duct can be plugged up with a piece of styrofoam you cut and fill in there just to stop cold air from blowing against a 1/8" thick piece of plastic right next to your warm roof vent!
I haven't documented my repair for this issue yet, but I bought a new AC roof vent (the circle shaped one) from FR and plan to install it into the bathroom ceiling and also plug up that opening to the roof vent area. When I do this, I will upload pitcures and post a new thread so keep your eyes open late fall when I do the work...I refuse to work it in the Florida Humid Summer because I end up sweating all over my work area!
