2006 Dodge Airstream Rear Window Replacement

[Donna Foxxx]

Hi. I have a 2006 Dodge Airstream Interstate Motorhome. I'm thinking about replacing the rear cargo door windows with the windows offered by Pennisula glass. They slide open - good for more air! Has anyone done this replacement? How difficult was it? Is it a perfect fit resulting in no leaks once the installation is complete? Any information would be appreciated. Our motorhome has the bed in the rear so I don't want to get one of the add on screening options.
