I purchased the Large Rack from Tom @ AMS jack in July/August; I took some pictures during and after the installation, I've been meaning to post them. Overall, a really nice unit, excellent quality. The Large rack also has pre-drilled holes for the Givi boxes, the smaller two units do not. I would definitely recommend it if you are looking.
It took about three weeks to get it, they did not have any in stock and I had to wait for them to cut it.
