Can a Toyota Sienna carry a 4x8 sheet of plywood?

Yes, a 4x8 sheet of plywood can fit in a Toyota Sienna, but the ease depends on the model year and how you prepare the vehicle. For the best results, fold down or remove the second and third-row seats for maximum cargo space.

For the best fit

• Fold down or remove the seats: To create a long, flat cargo area, fold down all available seats. In older models, you may need to completely remove the second-row seats, which can be heavy. 
• Slide seats forward: If you can't remove the seats, slide them as far forward as possible to maximize the space in the back. 
• Lay sheets flat: Once the seats are managed, lay the 4x8 sheet of plywood on top of the folded seats to make a flat surface. You can fit several sheets this way, but note that the front seats might need to be adjusted to make space. 
• Load diagonally: If the sheets are too long, you can load them at an angle. A 4x8 sheet of plywood will fit into the vehicle, but you may not be able to close the rear hatch completely. 

For the most efficient load

• Use the van's interior as a guide: To load a 4x8 sheet of plywood, angle the sheet into the vehicle and rest it against the back of the front seats. 
• Secure the load: Make sure the load is secured before driving to prevent shifting. 
• Check cargo anchors: The van has a cargo anchor to help secure the load, but be careful not to damage the front seats. 
• Consider using a truck or utility trailer: If you have a lot of sheets to haul, renting a truck or using a utility trailer may be a safer and more efficient option.
