My fire drills include grabbing the (I have a rear bed) bed spread and using that to cover the edge. I plan to remove the screws that keep the window from sliding so it will in fact slide out of the way.
I also practice opening the other E exit in the toilet room and actually climbing (at least part way) out onto the roof.
