Received my Sage Brush EX-L Pilot last Friday evening (definately more grey than blue, and more blue than green...but still a great color for this vehicle). Anyway, My wife and I take our dog with us on many occasions. What's the difference between the cargo tray vs the cargo liner? Honda's website shows a pooch in their photo for the liner (the tray is $100 less). Also, is the separation net enough to keep my springer spaniel from jumping from the back to the second row?
