We went with a 32" LED in a lift cabinet. We could go bigger, but the couch is only 5 feet away.
When we bought the coach, it had a big tube TV head banger right over the drivers' seat.
It was also the backup camera monitor (the inverter came on when you turned on the camera). I built a new cabinet from the lamp table that was where the lift cabinet went and bought a newer camera system.
