Do you use your sliding window at the front of your camper?

I've never used mine and my truck doesn't have a matching pass-through window. I have curtains on the camper window and they stay closed as does the lower blinds on the rear door, so it doesn't even get used for reversing.

Maybe in warm weather we should think about opening it for more ventilation, but because I tend to stuff things between the camper and the back of the cab I probably wouldn't get much ventilation either.
