Question Window fog/ cloudy

[Grizzlee]

Hello Travelers.
I’m about to pull the trigger on our first RV. Been looking at it for a few weeks and test drive it today. Almost positive we will buy it. Here’s my question. 2007 Fleetwood Discovery 39v the drivers side window is the most clouded and a few of the side windows are slightly clouded. It seems to be between two panes of glass. Is this a normal occurrence? Is it fixable without replacing the windows? Is there a magical procedure that only RV’ers know about? Or is replacement the only cure?
I anxiously await replies. It’s not a deal breaker by any means, but clear windows would be much preferred.

Thanks in advance!

I have one that is a little cloudy. Based on humidity it sometimes goes away.
My plan is to remove the window form the RV then remove the double pane glass. Re-seal it without separating the glass. Then drill a small hole on each side of the seal and inject nitrogen in between the panes to remove any moisture/oxogen. Then seal the 2 holes back up. Will see if that works.
