Yeah, there are two ducts already there and ready to use for the 2nd AC.
I am only missing the control wires.
The only place I did not check was within the duct-work which is sealed off with foil tape. 'Second Chance' mentions it could be there...I'll have to check when I get it out of storage in a few months!
I'm hoping to buy the equipment soon to get a good deal before the RV season kicks prices up. So I need to decide which direction I should go, ducted or non ducted, and what type of control I want.
