I have thought about a small window on each side. I'm still getting a feel for my inside layout. It's working pretty good so far the way it is. At this point I can change anything that I want. Once I put windows in I will have less flexibility. To answer your question: I haven't heard any noises that I need to identify yet but I also haven't had to sleep in a parking lot yet. Wilderness noises don't worry me as much as urban ones would! I'm not sure how stealthy a camper it would be now but a couple of windows would certainly make it less stealthy.
