Hi Ceasar and Oilburner
You are right in that the F11 has a flexible netting attached to the retractable load cover. There are three issues with this in that:
1. The load cover has a large rigid flap that sticks into the boot space which is now covered in dog slobber
2. The dog would slobber over the rear seats if I removed the integrated load/netting unit
3. Most importantly, I am not confident that the netting would hold a 30+kg dog in an accident at any combined speed so pushing through into the passenger areas, potentially hurting the dog and passengers
The official BMW dog guard is a metal grill that anchors into the roof recesses and is locked by the rear seat brackets. Much more robust. But for some weird reason does not work with my late 2016 LCI car. Frustrating.
Have a boot tray from BMW but I must say, the hatchbag looks pretty good though.
