Televisions- 12V vs 120V

Other than the obvious, what are the considerations? Will a 12V tv drain down the ship's battery real fast? How does the power consumption of a 12v tv compare to a standard tv running off an inverter?

Re: wall mounts... Do you remove from the mount and store the tv for transport, or leave it in place?

My better half doesn't believe we'll need a tv in our new TT, but I'm betting that after the first rained-in weekend, I'm thinking she'll change her mind.

What we got was a LED TV that runs off one of those transformers that plug into the 120v outlet (like lots of electronic equipment these days). With this particular TV, the little transformer converts the 120v AC to 12v DC. For a couple of bucks at Radio Shack, I splice a cigarette style 12v plug into the power cord, so now I can plug it into either the 120v AC plug or the 12v DC outlet. Inherently, using the inverter would use up more 12v power than hooking it up directly to DC as there is a loss of efficiency converting the 12v DC to 120v AC. Our 19" unit draws about 3 amps DC. Before this, we had a 13" tube TV that drew about the same amount of DC.
