I have fitted the cargo net from College Hills it works perfectly, but of course it is not a tray. How about a couple of plastic oblong trays/bins from Wal-Mart, which is what my sis-in-law does? A few months ago, when I asked the same question, someone posted a tray from a Volvo or was it a Saab. It fitted with a squeeze and I think the guy (Canadian?) posted a photograph.
