14V /35 Watt TV has to use 110 question.

I have the standard Airstream issued Samsung TV in my Bambi Sport 16. I would like to be able to watch TV on the occasional times that I boondock. That means going through an inverter in order to use the supplied 14v/ to 110v 35Watt power Samsung power brick. (They don't have a direct 12v cigarette type plug, I asked. I also can't find a 3rd party adapter since the Samsung plug is 14v / nonstandard.) That leaves me with this possible solution.

First off, I would need to get this wall plate power supply that has the antenna booster and a 12v plug.

2nd, I'd then use this 75w Bestek inverter.

When running this idea past the RV service guy I would use to install the face plate, he advised against it saying it was way too inefficient to convert 14v to 110, then back to 14v to run the TV. It would drain my battery. He went through the math that would require the conversion to work and questioned whether the wiring would even support that conversion. Is he right? If he is, then the only alternative (if I want to watch TV while boondocking) would be to replace the TV with a 12v one.

I've read posts where people have done this, so I am wondering is it advisable or no?

I'm assuming that the Bambi didn't come with an inverter.
This will work if you've got 2 batteries on the tongue you'll have plenty of power for this, but you will be drawing the batteries down and will need a way to recharge every few days.. I did the exact thing in the SOB I'm using this summer. The winegard outlet is limited to 8 amps so the 75 watt inverter is about as high as I'd go. I use a generator as well to keep things topped off, but don't always want to run it when tv is on.
If you're planning on keeping the trailer for a while consider adding a small hard wired inverter with a transfer switch for that circuit down the road.
When I click on your second link for the inverter it shows me that I purchased it a few months ago, same one. It does pivot but it's not quite 90 degrees so it sticks in front of my tv a little bit. Already had the winegard amp with 12v outlet next to the tv.
