[Snort]

Here are a couple of pictures of how I set mine up. I bolted two rails to the box mounting points. These accept the factory mount points on the Expedition seat. I mounted two ratchet straps to the rear rail and use these to secure the car seats. The back of the seat is basically touching the end gate with just enough room to put a short handled spade in between.

The tarp comes down in the back to the top of the seat. I also used some netting from a trampoline surround and built side nets. They are attached to pipes that drop in to the holes in the sides of the box. They stretch from just behind the factory roll bar to just in front of mine. This was done to keep branches from slapping the kids and to keep their arms inside.

There is enough room in front of the seat for a diaper bag and a cooler for snacks.

In the picture the side nets are in the loading position, not in the using position.
