When I purchased my new Hitchhiker 5th wheel in 2007 it didn't have a TV installed. It had been removed for some reason. I already had a home-type TV in my motorhome, which I traded in on the 5th wheel. The sales people offered to pay me for the missing TV and I decided to use my existing TV in the 5th wheel instead. The space where the original TV in the fiver was supposed to be was much larger than my home-style TV. I set my TV in the space and connected the necessary wiring (it was an AC only set, but there was a receptacle nearby). I didn't care about the appearance. In preparation for travel, I employed bungee cords to hold the TV in place. It remained that way for about 8 or 9 years until I had to sell my fiver due to a sudden disability. No damage ever occured to the TV during that time.
So the answer is yes, you should be able to install a home-type TV in your RV.
