Our new 2019 Montana 3761FL was in secured storage for the last 3 weeks. When I went get it, the pane less window next to the dining room table was broken in a thousand pieces. It was not vandalism. It could have been by a weed eater but the lot owner said there has been no weed trimming around the RV. Has anyone had a window to break because of the heat? How about a crazy bird flying into the window? Any other causes? Very puzzling!
