In researching the web, I came across several different size overhead tv/vcr units. These units are actually intended for a motorcoach or custom stretch limo applications but since my boat, 2005 390 Motor Yacht, has a hard top, I am thinking about installing one in my boat. They are 12 volt and I really don't have to worry about moisture since the entire cockpit area is enclosed. I guess my biggest concern is the viewing angle and how big a screen would suffice. I have been looking at the Jensen JE17FDTV, which is a 17" model and the Pyle PLRD195IF which is a 19" model. Does anyone have any knowledge about these units?
