How to tell dual pane/thermal pane windows on Arctic Fox?

Hi, I was talking to a person selling an Arctic Fox on craigslist and they claim it has the cold weather package, but I have some doubt about that, so I asked if it had the thermal pane (dual pane) windows and they were unsure.

Is there a way to visually see the difference on a recent (2013) Arctic Fox TC?

(I'm not local to where it's being sold and unable to go view it myself)
