Hi Wildglide,
The 26" Samsung TV in your 2011 looks like the same one I installed in our 2007. Back in 2007, Phoenix only offered a smaller 3:4 aspect ratio TV up front so we ordered our PC without a TV, then installed a 16:9 widescreen for a lot less money. If your TV has black raised control buttons that are practically invisible in the lower-right area facing forward, then we likely have the same TV.
Our 26" Samsung TV with the old video/audio RCA jack technology (HDMI not known) and fluorescent back-lit LCD screen, still works well with our original 2007 Executive head unit. We are pretty much limited to DVDs, unable to play Blu-Rays. Our TV antenna is the old crank-up Winegard, analog technology. It takes some doing to point it in the best direction to pick up free TV, then have our main Samsung TV scan and find stations, an involved process that we rarely bother doing. Campgrounds with simple plug-in cable-TV is an outdated luxury we have not experienced for a long time, hence we primarily depend on DVDs for video entertainment. If we often extend-stay in campgrounds, just hanging out a lot, that would be great incentive for a very serious upgrade.
Due to confinement against the fabric ceiling, the front TV ran uncomfortably warm so I installed two computer cooling fans controlled by a POT to lower their speed to quiet them down. They make the TV operate nicely cool. Power consumption from the over-all entertainment system up front has always been significant, with or without the fans running. When boondocking, with batteries in good shape, we'll watch TV up front only if the next day involves a lot of driving and/or the destination has shore power.
If I were to buy a replacement front TV today, I would select a frameless 26" to 32" with an external power supply, not 120V direct. Actual operating voltage is subjective to amps and watts, so upon bringing the TV home, I would immediately experiment with a car battery to determine if the TV will function properly from a 12V power source. Running directly off the house batteries will save energy compared to 120V through the inverter. Being lower power compared to our old LCD TV today, will benefit similarly.
Naturally, TVs today are much more techie. My favorite is screen-sharing a smart phone to the TV to watch anything off the phone, right on the TV.
Here is what we have today, installed back in 2007 or 2008.

Here is our PC-installed head unit with 5 speaker +subwoofer. The brand is Executive.

Also back in the day, I installed a Toshiba TV/DVD combo by the double bed. Naturally, it is much easier on the house batteries, so when we boondock, this is our go-to TV.

Our 2007 PC has not kept up with current-day technology in two areas, entertainment and on-board energy without solar or lithium, but we are happy none-the-less. If or when something dies with the entertainment system, that would be a good reason for a leap-frog upgrade.
