We were on road trip, 1000 miles from home and lost the right side of the big window in the slide. No idea how, broke and gone at next stop... After dozens of calls, etc. we finally had a guy ask us. It is the black privacy glass, yes, it is rounded, yes, and is it tempered glass, yes... Go to dealer and get a new window, YES the whole huge slide window with two windows in it. It cannot be fixed any other way. After deductible, window was paid for, but was expensive!
If you bought the trailer new, get on the service department and tell them they need to fix ASAP, not put you on list, that is why you buy new from dealer! We are lucky to have great service at our dealership! Have fun...
