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

I use it all the time... for fresh air when the roof vent is running and for make-up air when the Wave3 heater is on (in conjunction with an open roof vent). I find this window to be especially useful in wet weather.
I made a screen from a scrap piece of 1/4" luan plywood and some window screen mesh from the hardware store. It simply rests in the slider track.
