Nice pooch!!

If I may offer some advice.

I have to haul the Grand Knuckler around town as well as on some 1000 mile road trips and here is what works. I bought one of the BMW issue mesh cargo area dividers.

It is incredibly strong and well made with metal bars across the top, middle and bottom. It works 1/2 rolled up when the seats are up or it works at full length when the seats are down. When the seats are down, it attaches in either the forward position or the rear position. Look at your headliner, those tan squares open to reveal the attaching points. It effectively turns the back into the travel crate.

The dealer wants like 400 for the mesh divider. I found mine on e Bay for 125.

The dog loves it. The rear cargo area becomes his kennel. I use some bungees to store some items when we travel and put a small travel bed back there for him. He sleeps, sits up, chews on his toys etc...

I can post some pics later.
