Apparently new MH manufacturers think we would rather look at Giant TV's than the outside world. I love MH's with a lot of windows. When we were looking I was amazed at how hard it was to find one with large windows on both sides. Always loved the side aisle floorplans with the floor to ceiling windows in the hall.
To the OP, you could mount a camera on the outside of the MH behind where the TV is and rig it to display on the TV. Essentially you would be "viewing" a real time version of exactly what you would see if the TV were a window. Tech solution and less invasive. Sure it's not actually looking out the window - or is it? If the camera is placed to provide a view to mimic what you see isn't that sort of the same thing? A lot cheaper and less complicated and wouldn't invalidate your warranty.
