I just got mine today, ordered the soft cargo liner simply for the rear seat back protection. I had also ordered the rubber cargo tray, and was curious if they would work in tandom....and well they DO!!! I installed the soft cargo liner first. I was skeptical because it was only going to attach with Velcro on the liner directly to the seat backs. I didnt think it would hold all that well, but it does!!!. Its also really nice that it does not get in the way of the car seat latch system in the back and that you can still put the seats down in any configuration (just watch cause they are a little tighter to put back up). I then put the bumper flap on and folded over the bumper. Then I put the cargo tray on top. It was a little tight right at the seat backs on the bottom, but the accordion piece that other reference with seat covers, can still be lifted up and the cargo tray slides right underneath. Last I just folded the bumper flap back on to the tray. I'll try to take some pics in the daylight (im thinking its still going to be hard to see because its all black), and upload them soon.
ekcooper: Its smooth, but not real slick. I dont think the dogs will be able to puncture it with their claws.
dad of jon: If you had to pay for install time, you got hosed....It took me about 10 minutes to install...tops....
