I stack 4 tires where the rear seats used to be. Then I have one big tote for my helmet, shoes, misc stuff, and that goes in teh back. Then I have 2 smaller totes that hold brakes, tools, fluids, etc, and they go in the back as well. Then I have a canvas bag with the aluminum jack and torque wrench, and that goes in the back between the totes.
Then the tent, sleeping bag, tarps, duffleback, chair, cooler, etc all fill in the holes left in the hatch.
When done, its fairly full.
