What you've been waiting for,,,Transit campervan

I have liked the all glass look since I looked an Airstream Interstate.

However, it is a decision on form versus function. Here in Texas, if I were using electric heat at a CG, the smooth look of the windows is great. If I were parked somewhere colder where the only thing that would be heating my rig is stuff I hauled in, I'd go for the uglier, but far more insulating dual-pane windows.
