I find it interesting that almost every camper van out there uses small windows instead of the big wide panel factory windows.
I understand that it makes it easier to put stuff inside, but I've really come to like my "wide angle" views in my build. At the same time, others who have used smaller, well placed windows have some really nice end results.
In my bathroom area at the back of my van, I used wood walls all the way up, and put black felt on the outside-facing side, so from the outside, you just see a black section in the window. It has worked well for me.
I always get more ideas from looking at commercial builds! Thanks,
