I have the smart Cargo Cover (#10) installed, and the Large ROLA Cargo Container, which sits directly underneath. For me, it's the perfect combination, as I can just reach back from the driver's seat, pull the top on the cargo cover towards the rear to release it and retract it, then I can access what I want from there, without having to get out of the car. Of course, it's easier to store the things that you know you might want behing the passenger seat (and in the same area all the time), so that it's easier to get to. Reaching anything behind the driver's seat without being a contorsionist would be a real pain!! So I keep my windshield sun shade and CD case directly behind the passenger seat, and it's very easy to get to!
