The emergency windows double as regular windows. As an emergency window when you pop it the entire window opens. As a regular window just the sliding part opens.
Our Bighorn emergency windows work the same way.
DW & I attended a Life on Wheels conference a few years ago. When we attended the Pre-conference beginners classes they asked us how many have tried opening our emergency windows and more than half had not. The instructor told all of us to open them and make sure they work. The next day, out of about 20 people, 4-5 people said their window would not open. They also told us to actually open the emergency window and go out of it to see what it would be like. If we exited out of the bedroom that we (guys) should go out first then pull the picnic table, if one is available, up under the window to help our spouse out.
It would be intresting if there were an emergency information event at our Gillette Rally. Maybe Mac The Fire Guy could talk on this subject. Is he going to be at the Gillette Rally?
