How thick is that 32" Samsung? How stable is the TV when you are on the open road? Does it move around a lot? After a 2 hour movie, when you put your hand above it, is the area very warm?
I ask because our 7 year old 26" Samsung is the older thicker florescent back-lit type. The TV gets hot up top that it was a bit concerning for the life of the TV. I ended up installing a 5" computer style fan behind the TV to circulate the air in back which did resolve my heat problem.
What bothers me is that heat = power and I was wondering if the new thin TVs run cooler. That would help with battery reserves. When we boondock, we most often will watch TV in our bedroom on our little 19" with built-in DVD player. The batteries hold up much better that way.
