Totally serious, not as fun:
Yes, sleeping bag in a stuff sack in the bottom, in the sleeping bag compartment as a base. Clothes in a wp sack loosely spread over that to keep the height down. Ground pad next to that against my lumbar, also in a stuff sack. Bear can vertical on top of that, centered up. Tent and poles on one side of the can, stove, fuel and cooking gear on the other. Jacket in the kangaroo pouch. Raingear, maps, first aid and PLB in the lid. Everything else in various internal or side pockets. I love pockets.
I throw it in the garage when I'm not using it because I don't have a basement.
