The same situation has happened to a few houses I have very first hand knowledge about and it's always the glass that has the most sun light shining on them for the longest periods of the day.
I can't help but think if awnings had kept the direct sun off the glass if the fogging would have been less severe and took a longer period of time to show up not that it would have made it not happen at all.
From what you describe, your windows are toast.
The inside surfaces have been chemically etched and the panes and seals need to either be replaced or install new windows.
call Fleetwood and ask which window Mfg. made yours and the cost of new incl freight and call glass Mfg. for comparison.
There is a place in Florida called Suncoast that does a total refurb. for about $200/ window and you can stay in the RV while they refurbish.
