I was told by our dealer that we can add a second 13,500 BTU AC unit, mounted over the rear bedroom, using the existing exhaust fan roof opening. They just pull the existing fan, and drop in what they call a "chute" design AC unit. It does not tie into the existing ductwork - couldn't handle the extra air flow in any case. Rather, a directional chute points the cooling airflow, usually down the center aisle toward the front of the coach. They would add a separate 120-volt circuit to power it, adding an exterior plug-in. They estimated $2,500 turn-key cost. I am interested in thoughts from more experienced RV'ers who may have done something similar.

I did exactly what you are looking to do. I did the install with a friend. Took the good part of the morning and afternoon to do.
Getting the ac on the roof and mounting the lower unit to it took about 1 hour.
Running the wire through the wall, under the bed, out the floor, along the frame in conduit, and then to a new 30 amp plug took several hours
There was lunch and a couple breaks also.
Overall not a difficult job to do if you have the tools, which my friend has, and definately not $1500-1800 worth in labor
It works great. I use a 50 amp to two 30 amp dogbone adapter
