Though I normally am in a camper I do have a boat and recently installed a Marinized 12v tv.

So recently I have recently upgraded from an old fishing boat to a new boat and in doing so I have gained about 350sqft of cabin space . That isn't deducting all of the space the benches and small stove take up. The room is roughly 10*6*6 so not a ton of space but it is enough to move around in and sleep. Recently I bought a cheap tv from Circuit city and well it died in about a week of normal use. I suspected it was to do with moisture and salt in the air, I did some searching and stumbled across Marinized tv's.

I didn't know much about the Marinized TV's, so I gave the customer support number a call and it turns out they are what the big ocean liners use in the're cabins! I ended up putting one 15" in my boat cabin and 1 22in on a custom mount that I made for my Tow behind camper. Its a tiny camper and the tv is mounted on an adjustable swivel facing the head of the bed on the ceiling (to save floor space)

Anywho, for resource sake I'll link for you guys\gals.
