My only water leak (so far) was the AC foam seal between the roof and unit was improperly installed and began to leak after it had been on the road a while.
The Flourescent lit LCD TV's have a very limited viewing angle and are probably a bad choice for campers (folks laying on the floor can't see it at all; in my layout I have a choice to angle the L/R TV at the dinette or the couch to be watchable), but we are stuck with them.
Plasma TVs have better viewing angles than LCDs but draw three times the power.
The new LED lit LCDs are not much better; but some.
Forget 3D anytime soon (the active glasses type has an even tighter viewing angle), but there is a new type that uses the same "cheap" passive glasses used in theaters that is much better. I was reading about them from Crutchfield.
