Alright, so I tried a bunch of different ways to hang this thing and I'm still questioning it'* usefulness.

I tried the rear 4 *****, that would basically split the trunk in half, though It still stretches quite a bit.

I tried the front 4, which makes it "U" shaped.

And the method pictured I call "the Hamock", which you coould probably put a grocery bag in it and it would stay put.

I thought they were just supposed to go straight across the front of the trunk

Ya, it wasn't on when I got mine either. I prefer the "u" shape. I keep a blanket, a small "couch" pillow (Dont ask) my microfiber polishing cloths, a roll of paper towels, and 1 bottle of windex, and one bottle of Meguirs Quick Detail all lined up in it. It actually stays pretty neatly in place.

i have the U shape as well, all 4 attachement points near the Taillights
