Joe/Terry, with the outside TV door open look under the sink on a bright day. You will see that critters have very easy access to everything inside. Soooo, I mounted the outside TV to a panel with a small hole for the wires to pass through and connected that to the Seneca body. If I was smarter I would have mounted one side with a hinge and attached only one side of my panel directly to the coach body. That would make checking connections much easier.
Behind the TV I found that I could connect to the internal DVD player/satellite connection vs the outside DVD player.
