We just purchased a 32" Samsung smart television for our 26' trailer. The mount we got makes it easy to remove the television and put it on the bed while we are moving. This also makes it easy for the television to do double duty as a kitchen television when we are not using the trailer. We started with a 24" Vizio smart TV from Walmart ($188) and it was OK but way too small for my eyes so we returned it!
We went for a smart Samsung television. I use my cell phone as a repeater to provide an Internet connection for the smart TV. BUT!!! I have unlimited data on my cell phone account.
