Our trailer has movable sitting and places to watch TV ( from kitchen table in the morning or sofa at night, EG) so anyplace the TV is nailed down will be wrong for somebody watching each time.
We have the TV loose and can put it anywhere so it can be seen by everyone no matter what. All you need is long enough coax to the Winegard and an extension cord to the 120v.
When going down the road the TV lies on the bed (same as another poster above does) While camping, unless watching it, we can stash it (32" ) behind the (loose) sofa-bed. We can haul it out and sit it on a chair to watch it with DVD movies or TV broadcast facing any which way that works.
