Our 1973 amerigo
has a big window on one side of the front and it does open, same as all the side windows
, a one-piece jalousie (I prefer the multiple-part ones, but go fish)...the rock shield was apparently never raised by the POs and was just amazingly filthy inside. However, we've cut a big opening in it and will install a sheet of "generic Lexan" -- shield can be raised, then, window can be opened...painting that original weird green fiberglass white inside the shield.
Hoping to be able to see "through" the trailer when towing, and to have better light
and view when parked if we aren't able to raise the shield, because of wind, say, or only parking briefly. What's the point of a window that is permanently blocked? It's our back window that cannot be opened.
