I got a P.M. on this question, thought I would re-post for the newer members.
On my 3400RL, the escape window in the desk and bedroom had no screens, thus, no ventilation, so I changed out the windows to ones that have a sliding window and screen installed.
I am including a notation about removing the window for ventilation, I'll come back and link a slide show, showing how we did it.
Escape, dual pane, screened 36x22" part number is F-860-17653
Bedroom and office slide window, 3400 RL model.
Kinro is the company, the window is (WAS) around $230 or so, freight, packing and all. ($168.00, plus $20.00 for packing, plus shipping costs.)
Dawn is the contact, 574-848-9100
Tell her Jim Osbern sent you.
(This is an old post, just to tell about the screen)
I have ordered my escape window from the supplier, but meanwhile we need the ventilation, as the evenings here are in the high 60's, days in the 80's.
To remove the window glass, take out the two small phillips head screws-stubby screw driver please..., then slide the window towards the rear of the Monte, it comes off fairly easy. I would suggest some silicone spray on the top rail.
Sue made a screen out of a dollars worth of screen-like fabric from Wal*Mart, we used Gorilla Tape, (Get a roll, it's awesome) to secure it. I'm not worried about the rain, it's under the awning.
