Most of my gear is lower-weight (but not ultralight) backpacking gear. Space has never been an issue, and I usually carry enough extras to share if needed. Not visible in the picture (soft top is in the way) is the shelf I built to keep the gear in its proper place. 4 Action Packers fit underneath, two Contico totes + cooler fit on top, and chairs get set on top of that. Gear underneath is a friction-fit by design, gear on top gets 2 ratchet straps to keep it immobile.
