Hello and welcome! I have a 2009 base also. I use the hooks with a small diameter rope, maybe para cord that you can get at walmart, to keep things from rolling around in the rear area, sometimes to keep them standing up (like a 5 quart jug of oil.)
It's hard to get a knot to hold on that little hook, but a clove hitch with a small flexible rope will work if you pull it tight. See number 6 below.
