I do something like this.
I put one of the tie-downs in the middle of the track that's on the back of the bed. I put another one on the same track, but close to one of the sides. I put her leash through the one on the side, then loop it through its own handle so it's secure. Then I take the end with the latch and put it through the tie-down in the middle of the track and clip it to her collar.
It gives her enough room that she can stick her head over, but she can't even go far enough to put her paws up on the wheel wells on either side.
I imagine that it's possible for her to get her body over the edge of the truck and hang there, but probably only if I hit a really big bump at a high speed. I don't think she could put herself in that situation.
She LOVES riding back there. Under 40mph or so she'll stick her head around the cab and face the wind. If we're on the interstate she just sits in the bed and looks straight backwards. There's no way I'd trust her to stay in the bed w/o the leash.
EDIT: I also have a bed mat. I think it'd be mean to have her back there w/o one. She'd be sliding all over the place.
