I have the 19H and I didn't mount the TV because we didn't want to loose the space on top of the wardrobe. We picked up a cheap 19 inch set on sale at best buy. We don't use it every time we go camping. When traveling we wrap in in a blanket and put in on the seat cushion.

Been a camper since I was a kid, and that was a long time ago :)
From pup tents with no floors, to tents with floors and flies, to a pop up, to the expandable.
