We have a 2017 Thor Quantum WD31, which comes with a 15,000 BTU AC unit. Not enough cooling for our Southwest heat. There are other threads that address second AC units in general, but I am looking for more specific information. 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.
