Hi Maury,
The greatest energy hog 55" TV draws 155 watts which translates more or less to 16 amps from the battery bank. So one hour costs you 16 amp-hours

Thanks all.

Thanks all. It's not that big of a deal really. Tons of people do it especially since every RV built in the last 5 years or so has 120V TV's in them. My 300W inverter uses .26 amp DC, my 26" LCD TV uses 73W AC (there are lower power usage models available), the sat box uses 14W AC, and my Bluray player uses 25W AC. Typically, a movie draws 11 amps DC (using Bluray player, sat box turned on also). That's not much more than running the furnace (mine draws 9 amps).

From what I have seen several of the newer rigs actually come with a 12Vdc powered Jensen LED/LCD HDTV either 19" or 31". They claim their line is RV rated - Not sure what "RV Rated" actually means.
From my experience fixing hundreds of flat screen TV's over the years there are many good brands.
I am not endorsing the Jensen line

Slightly off topic but just to elaborate on mena661's post on inverter use, during the summer we typically go camping without hookups 4 or 5 times for trips ranging from 4 to 10+ days. Our mh (98 PaceArrow) has 3 house batteries (roughly 350Ah total) and a 1000W inverter. We still have the old 19" 120V CRT TV in front which I think uses somewhere around 150-200W. On a typical day, they kids will watch a movie before we put them to bed, then we'll watch TV for a few hours, we use the lights in the evening, then we use the microwave and toaster (not at the same time) to make breakfast and then we'll run the generator for a few hours late in the afternoon to recharge the batteries while we are making dinner (we also have a small (maybe 15W) solar panel but that really doesn't provide much charging.

8 alpenlites at a chapter outing. 7 had honda's running until they went to bed. the 8th (US) charged in the morning and the 2000 watt inverter did all we needed until bed time and morning cooking.

Ok, almost every RV.
