Internal (usable) figures, not external. Capacity is the geometric interior volume — real cargo never fills 100% of it, because pallets, dunnage and irregular shapes leave void space.
The table above is the box. What matters is how your cargo sits in it — how many units fit, where the weight lands, and whether you run out of floor or payload first. Enter your cargo and get the answer, free and without signing up.
