Dual pane windows - how do you know?

We got lucky on our current 5ver in that it has dual pane windows that we bought used. I am looking at a 2017 Cedar Creek Hathaway 38FBD. One of the options is dual pane windows but looking at the dealers online MSRP sheet (which I know they've typed up with their own prices on it) none of them that I've looked at list dual pane windows. Is there a way to tell by looking at RV if it has them? We will not buy new, but I want keep this model on my list to consider in a year or two.
  • Hold a light or candle near the glass and look to see how many reflections there are. If there are 2 it is dual pane.
  • Shine a light or light a lighter next to it; you will see one or two reflections depending.
  • Have someone outside put their finger on the pane, and you put your finger on the pane inside. Is there a gap larger than the thickness of the glass?
  • If you look at the window's edge you should be able to see the divider strip between the two panes. There should be an exterior seal, a pane, an interior separator, a pane and the interior seal.
