Hey Donneyboy,
From what I can see, the installation looks like a straight bolt in job.
The only reason I am seller is to get another 1.5 inches on headroom for my dog. He's still growing and it's a little tight for him back there (he only rode in the X5 once and I had a cargo mat down, so no worries about dog hair

) If I wasn't planning on putting my dog back there I would keep it for sure, I think it's an awesome feature!
I'll try and take some pics later.
PS - I'm in Santa Barbara, just down the road. I'll be home all day installing a trailer hitch if you want to come by and take a look. If you like what you see, we can do the trade/install on the spot.
