@NMW... I'd settle for a blue ray player and 6ft. HDMI cable to the TV...might even be amenable to a sound system that doesn't sound worse than a boom box on 4D cells.
It really would be nice to have some prefab channels connecting top & bottom so we could mess around and customize for our needs since there is so little opportunity to do that at purchase time.
Like most things... someone in the market will do it... and then everyone else will follow to catch up. Kinda like 50 amp pedestals, on site sewer and wifi in the parks.
