I measured the end of the truck line as it goes toward the closet out of the A/C unit and cut a hole for another register. You will need to line the area with Foil Duct Tape as there may not be any in the new area.
I also added a second register in the duct as it goes toward the bathroom, did not do much good.
I also opened up the area (cut away foam to make more of a funnel) where the Plenum Chamber on the A/C unit feeds the duct and then Foil Taped it too.
As other have said, also be sure the divider on the A/C unit between the A/C Intake side and the Output side is sealed good so the Cold Air is not going back into the intake and causing a premature freeze up.
These units love Air Flow, the more the better.
There is a freeze sensor on my coils but it does not seem to work as it will freeze solid and the compressor is still running.
