Sky Lights
Regarding the sky lights, I am going to tell you that our supplier, ALPHA of Elkhart, IN may has a tinted, or smoked version of the skylight, but when we put it in, it proved to be more transluscent than the opaque white one.
I think the shade, or the suggestion of the tinted vinyl material may be good ones. I would also bet that you could get a local auto window tinting company to come out and do your skylight for not too much money. It would be very thin vinyl and could applied right inside your coach.
