Thanks for the ideas.

I doubt I will be installing any permanent cargo boxes. This is still my daily driver. Even if I did, I'd still need to figure out what to anchor it to.

I like the wire mesh cage idea, like in a cop car. But it would need to be removable so I could still bet to the third row seat, or put a piece of lumber in lengthwise, etc.

I think the main challenge will be to install anchors, and after that, the actual cage/net can be added. I am going to poke around to see what sort of anchor points there may be under the floor. I figure a seatbelt is anchored with a simple big bolt, so there is a way to do it.

I do have six small anchors on the floor back there, but I can't tell how solidly they are attached. I'm guessing not very. I'll try to get a look at how they are mounted. Maybe I'll be surprised.

Keep any additional ideas coming! Thanks!
