Hank you are correct you're losing a lot of velocity due to friction of the ductwork, the 12000 BTU concealed duct we have above the refrigerator is the major source of cooling for the coach front as cold air falls, it also helps out the bedroom and sometimes I even turn off the 18,000 BTU back there when the coach gets in the mid-70s then turn it back on when we go to bed. It may be a little bit of work and pull some lines but putting one of your evaporators above the refrigerator is the direct exchange of energy in the location that you're trying to cool.
