On the FROG (Forest River Owners Group) facebook site there have been a few instances of windows being cracked from a variety of reasons. It is a concern for me as I'm planning a trip to Alaska and if one can be cracked that is the place. I also worry that if I keep the trailer through the next redesign and need to replace the window the current window may not be manufactured anymore. FYI - Forest River completely changed the front cap design after 2016, so it will happen eventually. I am going to find someone that can make me a protective cover. There is a company called Clearview Products that makes a clear protective film that they say will protect the window. They make it specifically for the Rockwood windows. I'm skeptical, but it might help.
