Looking for a web site that describes "frameless windows" being touted as a plus in some RV's. Best I can determine is that they are double pane? What about opening mechanisms?
Re Broken glass......Had 6 of mine replaced so far (2.5yrs). They have to replace the whole frame and glass. You can't just replace the glass part. (maybe you can but that's not how mine were done) 1 had the seal between the dual panes leak and 5 were replaced trying to get water leaks to stop. Mine were Lippert (Kinro). I heard Hehr are much better.
