Dave and Cheryl,
Our emergency windows in the bedroom and the one over the desk both have screens on them. The lever slides through the screen and then locks. Ours is a 2006 so I don't know if they have stopped putting them in the new 3400's.
The screen is on the very inside of the Monty. We just put up solar stuff to help reflect out the sun today..... since we only have one AC.... my Christmas list will have a second AC on it.
Jrjones,
All of our windows in our 3400 have a screen on them even the kitchen window that is really little. All of the vents in the roof have screens as well.
