How many pallets fit in a Sprinter van?

What changes the answer most

Stacking changes the answer most: if two may go on top of each other and each loaded pallet is at most 39 in (99 cm) tall, 5 pallets fit (not 8: 8 × 660 lb (299 kg) is over the payload).

4 pallets × 660 lb (299 kg) = 2,640 lb (1,197 kg), against a payload of 3,450 lb (1,565 kg). Each one may weigh up to 862 lb (391 kg) before the payload, not the space, sets the number.

The door is 61 × 73 in: a piece up to 73 in (185.4 cm) tall and 61 in (154.9 cm) wide goes through — the 40 in (101.6 cm) side of this pallet passes with room to spare.

What we assumed

• Pallet size 48 × 40 in (from our sourced pallet table), loaded to 48 in (121.9 cm) tall and 660 lb (299 kg) each.
• Stacking: no — nothing goes on top of a pallet.
• Pallets may be turned on the floor (long side along or across); they stay upright.
• Inside size 173 × 53 × 79 in; clearance kept: 2 in on length, 0.8 in across, 0.8 in up (so the door closes and cartons may bulge).
• Door check: on — every box must pass the 61 × 73 in door in the way it is placed.
