I just updated post #1 with more boxes.
Looks like the Alu-boxes and Milk crates are the most efficient hard boxes so far.
I started thinking more seriously about this, just because I was surprised that the milk-crate was so "low" at 80-something percent. I realized part of the problem is the "wall" thickness compared to the volume of the container. If I constructed a crate similar to a milk crate, but with expanded dimensions, efficiency starts to climb up to 85% or more. Something about the size of a Rubbermaid tote with vertical 1/2" walls is ~85%.
Going bigger or decreasing the wall thickness should improve things even more. I'd already considered making (or ordering) some custom-sized wooden boxes, just to maximize the use of my existing space - mostly to eliminate the wasted gaps BETWEEN the standard-sized boxes (e.g. 2x 16" wide tubs in a 34" wide space)
I'm starting to think that something like a 1/4" or 3/8" marine plywood "tote" with fiberglass fillets in the corners and epoxied would be damned efficient. My storage area has good protection from moisture and dust when the vehicle is closed up, so I don't need airtight seals or even necessarily lids, unless I want them to double as seating.
Given how easy it is to order premade drawer carcasses online these days, I'm starting to think about using that service to make me some deep "drawers" and putting some rope handles on to make them into boxes...
