Simon’s comment about ductwork leads me to a PSA. Starting with we all view the posts with the picture of our own rig in mind. The Dometic units don’t have duct work at all, except for few which have a unit hidden in the kitchen cabinets. They are the OG mini split, with an outside condenser and an inside evap. The SCS units that Jack, Arch, and Hank(you have been outed) installed are a completely different animal. The condenser and evaporator are contained in one large box. The cool air is ducted into the coach. Given the ductwork runs in the basement most of the length of the coach, there is plenty of efficiency loss. Plus on the SCS units, since the hot side and the cold side are in the same space, there is some transfer of heat to the cool air we are trying to make.

The point being that the folks with Dometic units will face an entirely different set of challenges when installing mini’s than the folks with SCS units. I make this point so that when reading the mini posts you can make the distinction. I make these comments having owned a coach with Dometic, and owned one with SCS.

Dean is on the right track with utilizing the interior spaces where the Dometic evaps are located for interior ducted mini. The challenge in my mind is deciding which bay or bays are going to get serious modification to allow the install of the condenser(s) because the condensers are NOT going to fit where the existing Dometic condensers reside, as Simon and Dean have clearly stated.
