Hey there! You seem to have a great bit of knowledge about the AC systems on the Montana's. I have a problem with my Dometic Duotherm unit that no one of the supposed techs know what to do. Tried to replace the existing 15,000btu unit with the recommended by Etrailer Advent unit. Found out it is not compatible. I'd appreciate your help because no one else seems to have any idea what to do. Thanks.
