Curved Windows
A lot of the detail work on Avion truck campers is top notch. But windows have come a long way since 1970. After extensive work resealing and reenforcing many of our camper's seams, one of the few remaining leak points is the windows. The current windows along the body are split into two panes. The larger top pane does not open. An understandable choice given that the surface these windows are built on is curved. Framing out a curved window pain and frame that opens and is fit for weather and highway durability would be a huge challenge. So, only the lower pain opens. It is a section just low enough for the pain to be flat. But this also means it is a very small opening: just enough for a little venting.
