Dobbs Express, The window I"m talking about is in pictures 1, 2, & 4 of 4 in your post. It is located on the opposite wall to the bathroom wall on the drivers side over the bed. It looks like there's a large notch cut out at the lower right corner of the window.
Hi: TAfraser... I think those notches are the supports for the RV blind cords. There's a plate with the buttons on them that form around the corners of the windows. The blind cords fasten to the buttons. Alf

Jim, you've got good eyes. The picture is low resolution so when I zoom in it gets too blurred to make anything out, but a fluorescent light makes total sense. Thanks guys, I can now move on to the next mystery, whatever it may be.
