the tele will NOT work from ANY AC current outlet on battery power...
in fact NONE of the 115v AC outlets are HOT on battery power...
(for example is the MICROWAVE clock/message center ON?)
unless the unit came with the 'inverter' package, in which case 3-4 AC outlets have juice.

the tele WILL WORK using the round
12v outlet (right near the antenna/cable connection), with a small (150watt) inverter...
the typical lcd 19 inch used in these trailers draws about 90-110 watts, so WATCH the battery levels...
(most of the tv sets have an "ENERGY SAVER" mode in the set up/menu that will reduce power consumption to 60-70 watts...)
