Ok, I was sort of guessing at your approach based on the other clues. Please take my comments as intended. I am NOT trying to dissuade you, criticize the approach, or take you in a different direction. I am just thinking out loud.
I think you realize from your research that the Dometic AC units are in fact the forerunners of today's mini splits. Of course they don't have the inverter driven variable speed fans and compressors that make the minis so efficient though. So my out loud wondering is can you mount the outside unit where the existing outside unit is currently located and also mount the inside unit where the current inside unit is mounted? You would have to carefully consider the physical dimensions of each unit and space. You might even have to repackage them a bit. The reasons for my questions have to do with the amount of work involved. If you could utilize the existing locations for the externals and internals then you could utilize the existing lineset and the existing power supply. You would not have to move the gen blower, and you would not have to get ducting through the floor and into the coach. It's just a thought.
Second out loud thought, is why a mini split instead of traditional roof airs? Some folks are attracted to the minis because of the energy comsumption, and foresee installing lithium batteries to possibly power the AC. That plan falls apart when they realize that they need a 56V lithium pack and inverter to make it work. The expense of such a conversion is prohibitive.
And third, we have owned three coaches. One with the Dometic, one with the SCS basement air, and one with roof airs. The Dometics were by far my favorite for cooling and noise. My bride does NOT like to be hot. The kids nicknamed the coach with the Dometics, "The Meatlocker". We wore sweatshirts anytime she was in the coach because she kept it so cold.
Again, just throwing stuff out while you are in the planning stage. I have a wee bit of experience with the units in the coaches, and I am just trying to help you make it work. And to keep your bride cool too !
