Some of us carry less and some of us carry more.
I'm a carpenter/renovator on the side - so I have a fair bit of tools I move around and the Runner is the mule that gets to haul it.
Post pics of what you usually have in your 4Runner, whether DD or not.
Air compressor and two canvas shopping bags: one filled with tools, the other filled with recover gear (tow strap, ratchet straps, flashlight thingy, jumper cables, etc). I'm thinking about making a cargo door to store them behind the interior panel instead of out in the open. I drive like a nutjob and sometimes dump my tools out of the bag
