We have been camping for a couple months, and the other night (in 37 degree weather) one of the windows fell off the top track. We resecured it, and when I inspected it in the morning, it appeared as if there was glue on a plastic track that failed and came un-bonded from the window itself. There were also two black end caps that I found on the ground. I compared the mount to the other side window, and verified that this was also coming loose, but not completely separated yet. Has anyone else seen this problem? Has Nucamp addressed it?
