I know that just like everything else people's experiences and opinions are divided on the Cargo Tray. I'm not sure if I want one or not. I do have two large german shepherds though and was wondering if anyone else has used the cargo tray with large dogs in the back? I figure I could wedge it somehow so when I opened the back it wouldn't move under them as they jumped in/out and cover it with some loose laid commercial carpet just for a bit of grip but what do you who might be in this situation think?
