I found in both my Wilderness and now Sunnybrook TT that both manufacturers wired the TV's together on a single circuit. 12v tv's are few and expensive, regular tvs more affordable. I bought for my fist TT a 1200watt Xantrax inverter and disconnected the television circuit from the shore power box. Put a plug on it and plugged it in to the Xantrax. Now with my Sunnybrook I did exactly the same thing but with a 2000 watt pure sine wave inverter. The Sunnybrook also captured a couple of outlets. We watch tv, it powers the satellite, charge phones ipads laptops, make coffee. I have the remote on off switch and just turn it on. When we are plugged into shore power, the tvs use so little juice its no biggy and the onboard inverter just charges the batteries. We dry camp as much if not more than fhu, so this works for us. Also I have two Trojan 125's 6volt golf cart batteries. So we buy whatever tv we want I have a 24 in the bedroom and will be getting a 32 for the living room.
