Hi guys this is my first post to the forum. I just pulled the camper out today and my kitchen window is cracked up by the hinge. Apparently dometic windows are Seitz windows? I need to replace the glass/acrylic. The trailer is a 2015, but I don't see any info in the literature for the windows. I was pretty surprised to see this issue as these windows are very highly rated. Luckily it was the smallest window on the trailer, had it been the one in the slide I would have been very ill. Is this common for these to crack? The trailer is inside stored unless it is out on the road. I use Plexus acrylic polish to clean them. We use it on airplane windshields all the time and it is designed for acrylic and polycarbonate. I guess Monday will be the judgement day. Have a great weekend to all.
