I don't think tha Monaco would have piece of glass available as it would be considered a hazard.
My thoughts.... You CAN remove that piece of screen while traveling (at least on our models) and attach the screens to the bottom part of the screen door.(Many people do not know this) This gives the passenger a clear view while traveling on the road. When you get to where you are going - put the screen top back up to keep the bugs out while letting as much air in while "camping".
If this is not part of the reason - I would still consider putting plexi-glass in instead of glass - safety for all involved is the main reason - PLUS it costs nothing -so it is cheaper!
Folks - let me know if I need to show some of you how I remove the top screen - and lock it into place in the bottom section -
