I have yet to see a 420 "in the flesh". Only pictures.
The pictures I have seen, there is nothing outside on the patio wall. No TV, stereo, etc.. Has anyone seen one to the contrary? I'm sure things could be added after the fact but I was just wondering if this is the norm for this model?
It can have a TV mounted. The mount, ac outlet, and cable outlet are between the doors and I believe you have to remove the TV when you close the patio. (Or before it rains...) See from about 4:50 on in this video.
