Run TV on an inverter?
We just bought a class C motorhome. It has a TV but it’s 120V and requires the generator to run all the time your watching the set. We have an inverter that’s 200 watts. I’m thinking of trying to run...

OP, any chance you'll be upgrading your TV at some point? Lot of 12vdc TV's available these days. Lot more efficient vs. the same size 120vac TV being powered with an inverter.
Additionally, folks often do not realize with the TVs with an external 12V power supply that those TVs are designed for COMPUTER "12V" (11.9V-12.1V) and never were designed or intended to operate from a 12V BATTERY which can have voltages from 10.5V up to 15V..
Honestly, running a TV from a inverter is not going to kill you, not going to use a lot more of the battery and are cheap and plentiful to find and buy and you WILL get far better TV than the ones marketed as 12V..
The loss on 12 volts to 120 volts and back to 12 volts is typically about 30%.
I bought a 12 volt laptop adapter that converts 10 - 24 volts and stabilizes it to 12 volts regardless of input voltage or (within reason) draw.
The cost was $29 and the loss is well under 5%, win, win.
