Why, yes, a lot of us have changed out our door glass from the opaque to dark tinted glass and what a difference it makes. Camping World sells the kit for $119.99, part no. 74221, and it ships from a third party in 2 boxes. The glass comes in one box and the tape and other stuff in another box. It took me about 45 minutes to put it in, not hard, but I was taking my time and making sure the sealant tape was done properly. It sure is nice seeing out that door now and at nite we use a reflective foil blind to cover it; we used Command stick on hooks on the door just above the glass and my wife taped cloth loops to the top of the reflective foil with velcro. All in all, a great project. Hope this helps. Pictures later when internet works better.
