don't know if this would help you out.... I just picked up a quilted cargo cover from Orvis to isolate dog hair and sand from the beach. On mine, width-wise it's just wide enough to go up the side of the cargo area about an inch or so on each side, and pretty much covers the back of the seats all the way across. Just about perfect for a defender. It attaches to the back seats by way of the headrests, and has a center flap, double zipper for the fold-down center section of the back seat. All around, well made. Length-wise, it fits from the back door, to up over the seats and a 2-3" wrap around when the seats are folded down (that's on my 110). Perfect coverage for me with a couple dog beds across the seats to protect the doors. Nice soft quilted surface with a little padding, and a backing that's supposed to keep it from sliding around & in place. From the looks of your pictures, it'd come down the rear of the cargo area to just somewhere over your cargo mat in the back. You'd want to measure for that, to see if it works. That would be the XL size. Just something I found that has a good fit.

This looks great! What dealer did you order this from?

 

you asking me about that quilted pad?

 

Personally, I could use a new Cocker Spaniel dealer.
