Jim,
The TV screen is tilted at about 15 degrees, making the top of the TV box about 11 inches deep and the bottom is 4 inches deep. Since the cabinet is so thin at the bottom and about 4 inches off center to the driver's side, there is no clearance problem when you go in or out the door.
If you install a 32 inch LED model, you will not have to remove the current TV cabinet. You can mount the new TV in the center section of the cabinets above the dash and against the current TV cabinet. You then just have to add doors and shelves to the original TV cabinet for component storage.
I will be at the Steedman, Branson, Oklahoma City, Amarillo, and Chama rallies in September, 2011 if you would like to see my installation before you start on your coach.
