That would depend if you want to run the TV off of 12 volt DC or just an 120 volt AC TV. The TV is only limited to the space above your refer. Look around before you buy. Most RV TVs are basically overpriced crap. I bought a new Samsung 24 inch to replace the factory installed Jensen for just under $200.00. The Samsung is a smart TV with a web browser.
Best Buy carries a brand called Insignia. Some have built in DVD players and the one we had in our last trailer worked very well. This brand is a 120 volt TV but actually has a transformer that converts it to 12 volts. There may be a way to convert it to 12 volt.
