What I Did
I struggled with the same issue and ended up locating mine on top of the "cooler" storage locker using appliance hold-down gizmos from West Marine. We hardly ever use the big cooler that came with the boat so this works fine. I installed an addtional 120v outlet inside the storage area and bought one of those portable 12v power supply/battery chargers/air compressors ($59 on sale). TV cords run through a hole drilled in the liftable top. When in the marina, we use the 120v while the 12v charges; when sailing, the portable 12v power supply gives us about 3-4 hours.This location provides good viewing for persons in the v-berth and on the settees (important since I have 4 kids). Also, with the appliance hold-down things, the TV/DVD can be stowed away when counter space is needed. DVD's, games and controllers are stored in the cooler space; everything is easily removed in the off-season for use elsewhereNot the most elegant solution, but it works well for us and didn't take a ton of work. Other ideas I considered either didn't provide enough viewability, took up too much headroom, or where too complicated to provide power for, etc. One more thought: I opted for a 9" TV/DVD player. They're more expensive than TV/VCR's but are smaller and the DVDs take up less room.Good luck and let us know what you come up with. I can change my configuration if I hear a better one.
