There are 2 crank out windows adjacent to the dinette in the 31UL. When you turn the handle to open the window there are two bars on a track that spread and cause the window to open. One of the bars came off its track so while I was on a ladder trying to put it back in the track the whole window came off the hinge at the top of the window. I couldn't figure out how to get it back on. Thankfully, I carry a roll of good old Kentucky chrome, aka ninety mile an hour tape, which held the window in place for the 450 mile drive back home from Door County, Wisconsin. Taking it to my dealer next week. Anyone had an experience like this?
