Welcome to the forum.
Some BS owners have replaced window for better ventilation for you the egress should help you also.
I have put many of their MOD's in
QT's # 3 second page, I will see if I can find the window replacement.
Here it is only one mod of many mod's for BS, should look them all up.
Here is
another one you will be needing some time in future.
Enjoy your coach and safe travels.
