We are interested in a R29 classic, and have a question about the AC. We will be cruising mostly in Florida. I see that it has a 16kBTU unit and a 10kBTU, are they separate and are there 2 compressors? Where is/are the compressors located? Where are the cooling units located, and where are they ducted? Can only one AC be on? We like things cool, so I imagine the AC (maybe not both) will be running most of the time while underway, dockside and at anchor? Thanks, Mark & Jane
