That doesn't look bad. I miss my saddlebags and I'm not sure I want saddlebags on my Stryker. That said, this would help with the occasional ride where I need some storage. How has it held up? Any loosening up or shifting? Just how much can you load up?
Here is a bunch of pictures from different angles. If you need something specific just ask. And it was kind of a pain getting it on the backrest. Still slides a little but that was using the poles that came with it and I still have a bunch of straps and buckles that came with the bag for other mounting purposes.
