2023 Toyota Sienna Long-Term Update: Cargo capacity is looking studly

I'm back with my final update for the 2023 Toyota Sienna. When we last checked in, I promised I'd see about loading building supplies into our long-term minivan despite its most glaring cargo deficiency — the lack of a removable second row. This holds the Sienna back from carrying large items that minivans otherwise excel at transporting. Fortunately, if your project's not too big, it's possible to carry some fairly large items without resorting to a roof rack. Here's what I found.

Upon first glance, the aisle between the Sienna's second-row captain's chairs looks like a perfect channel for holding 2x lumber, but as it turns out, it's just shy. This is a scrap 2x6 stud I had leftover from a garage project, measured at 96 and 3/8ths inches long.

If your load isn't too light, you can rest it on the cupholder (see below) in front of the second row; this will allow any 8' lumber to juuuuuust clear the rear door (above right).
