Here's a tutorial on replacing some of the dual pane windows on Winnebago products.

While the window you are replacing is different the principles remain the same. There are instructions on page 10 for determining the exact part number for your window. Be careful when going to the Winnebago site. There are 2 diagrams, 1 for single pane windows and another for dual pane windows.
I followed the instructions when identifying the window for our motorhome and they worked perfectly. The people at Atwood were extremely friendly and helpful. The lady that actally takes and ships the orders works from 5:30 AM to 2:30 PM Central Time. She is very knowledgable and will help you through the process.
Just a caution. If you decide to do it yourself make sure you do it in a heated garage or in warm weather if it's done outside. The process is straight forward but the butyl tape that seals the window in place gets stiff and extremely hard to remove in cool weather. We did ours this fall when it was 50*F. It took qite a bit of time to remove the window without damaging the frame. Also the residue left on the coach was difficult to remove. In weather of 70*F or warmer it should go much easier.
Just a note, the nmber in the tutorial is no longer in service. The correct number is at the top right of the Atwood Mobile home page.
