I just got this, and I painted black, I would like to add some panel or AC to get cold and some fresh air if posible, how can I cover that window to be more stealthy?
if you think about any other thing to prevent people noticing that I am living inside it will be highly appreciated
I would add side vents, they sell them in home depot and just paint to match your van. But you would have to cut holes on side of your van, put them high enough and you will be good to go. On mine the side vents feed a swampcooler. With side vents they are less noticeable, if you have roof vents and they are open people will think someone might be inside. If you have roof vents I would take the covers off and put a solar panel over them, the panel will prevent rain from getting in.
On my windows, I covered them all with foam insulation. At nightime they don't let any inside light go out.
