I unfortunately left my bedroom slide-out frameless window open (in pushed out position) and then took off on a trip. Stopped about 2 hours later and realized the window was missing. Had to duct tape cardboard into the open space for the rest of our trip. I called Cedar Creek and they replaced the window for free! Not sure why they did that, but we'd owned the Silverback for just 4 months when this happened. Plus I told them I'd come down and pick it up since we live about 50 miles from the factory.
The surprising thing is that the frameless window comes in a frame. I couldn't just replace the glass portion, I had to replace the whole thing which meant I had to take the old frame out first. Once I got started on the project it wasn't all that difficult. I did use a fair amount of caulking around the window frame to keep water out. It's been in for over a year now and no problem with leaking.
