Your intuitive structural sense was pretty good, but as it should be. . . over engineered!
I like it when contractors propose solutions that make sense. It made my job easier.

Doing a quick calculation of the compressive strength of each plywood box, it looks something like this.
Assuming a 8" x 12" box, the vertical sides are:
12+12+8+8+8+8 = 56 lineal inches of 3/4" plywood
56 x 3/4 = 42 square inches
Compressive of strength of plywood parallel to face = 4,500 to 6,000 psi
42 x 4,500 = 189,000 pounds
There are other factors too consider, but the boxes certainly seem adequate for his needs.

Useful & the plywood is rather attractive.
Question: How easy (right word?) is it to handle the boxes with the D-rings? Think I'll do something very similar but would prefer a pull handle kinda like this, big enough to get all my fingers around.
