Dual Pane Windows - how common?

[RRman]

Thanks to all who replied! As with many issues in real life and RVing, there are many different valid opinions. Certainly Dual Pane offers some advantages, even if slight. What really concerned me would a Montana without this feature "fit-in" as the norm and acceptable and the answer seems to be yes.
Out of about a dozen used Montana's I've found online for sale, only one mentions this feature.
One can always add professional or homemade "storm" windows if this becomes a priority. Perhaps a suspension upgrade would take precedence for example, or some other improvement like the second AC several have suggested. And fortunately, the ones I'm focusing on have slide toppers, so no need to enter that debate!

Have a great Memorial Day Weekend!

Now we may not like the Data, we may not agree with the data, we may not accept the data... we can even complety disregard it...but..it never lies........ BUT IT CAN BE WRONG!!!!

The world is full of incorrect data. Any Trades person out there can tell you that the some of the information (data) that we have been taught at Trade school will not work in the real hands on world. How can this be? The people that are chosen to write the trade manuals may be good at writing trade manuals but they are lacking experience with using the tools on the job.
