We use a 24", though keep it stowed when not in use as we very rarely watch TV when camping.

“Most folks are about as happy as they make up their minds to be.” — Abraham Lincoln
We put in a 24" RCA TV with a built-in DVD player from Best Buy. It was on sale for $CA129 and has worked just fine. We stow it beside the bed for travel. A bonus is that it runs on 12V, or 110 with the included wall wart.
The mount works well to swing the unit around for viewing from the bed or the dinette.
