One thing to remember when purchasing a TV for the RV is to look at the viewing angle, if you can go to the store and sit lower then off to each side to see what it looks like at those angles.
Most times in a RV you wont be looking straight on at it. I found out the hard way after buying and returning 2 TVs, that sometimes at those angles the screen is washed out or black making them un-viewable.
After buying and returning a Samsung and a RCA I found a
Insignia that has a much larger viewing angle, 160 horizontal and 160° vertical viewing angles.
In my RV with the TV in the front or the rear bedroom you have to look up at it. This TV works great in both areas. The DVD quality is excellent.
