But it's a 2015 in the sig. Call Jayco, they won't sell it to you but may look up the part number for you. Only a Jayco dealer can order from them but you having the part number will help. There may even be a sticker on the frame somewhere with clues.
A local glass company may be the quicker way to do this. It's amazing what they can do sometimes. An auto glass company vendor of mine when I was working just measured, ordered, and installed 2 double pane windows in my house. Glass is glass, that's what they do.
Also look at a similar window on your unit, it may have a manufacture id on it.
