I'm not surprised at the fact that rigs are getting more televisions. This has been a trend for at least 2-3 years now. A couple years ago, when I saw eight TVs in a toy hauler fifth wheel (one behind a hatch by the door, on in the living room, two by the bunks, one in the bedroom, one in the garage area, and one intended for the "porch" (which was created by flipping down the tailgate, adding rails.)
To me, I find it pointless. However, adding electronics like TVs is inexpensive.
What would be nice would be real changes: Truma water heaters and furnaces, for example. Daewoo's Mini-Drum washer that mounts on a wall, with a similar small dryer. Have the roof covered with solar panels, so the house batteries would be always ready to go.
