Can you share few pictures?OP...... I don't want to curve my windows that much when I don't have too and I store the window bag behind the FRONT seats. What your are doing is an option and glad it has worked for you. With the window bag hanging from the "front seat headrest", there is not enough room for the window bag when the BACK seat is in the up storage position in our jeep. Now with that said, if your FRONT seats are slid forward enough, there could be enough room behind your FRONT seats and with the BACK seat in the stored position. My driver's seat is all the way back and my wife likes hers all the way back also. The front seat backs are right up against the stored back seat in our jeep. We keep our back seat in the stored position so we have more room in the back for groceries and other stuff. If or when we have 4 people, I will have to look at options or take the Pilot.
Nicole is referencing to taking the top, "it", down and having to do "something" with the windows.
I will add a disclaimer to my above statement.
