I have a 1918 Wildwood WDT201BHXL, we've actually only used it twice in the last year, last time in January. It's stored under roof.
Monday a friend asked me where the back window was. I looked and the right rear window over the bunk beds was GONE.
No window. It looks like all the rivets holding the hinge let go. No scratches on the body or window surround, nothing ripped, scratched or missing except the window and the lever holding it shut.
I called the dealer, who was bought out, but the new owner said he will look into it.
Has anyone ever experienced anything like this?
