I have recent;y purchased the 2014 Solitude 379FL and love it. I have never hooked up to a cable source but, I will be in the next couple weeks. I just installed a TV in the pass through and noticed two Coax cable hook-ups. Is there a reason for the two? Also in the wet bay I have 4 hook ups can anyone explain what the four are for? (Bedroom, Living Room, Pass Through and Cable). I would appreciate any help I can get.
