Someone pointed out that a lot of US builders will drive pickups truck, and that it's kinda doesn't make sense, why don't they drive a van? Depending on the trade and location builders and contractors here will drive something like a VW Transporter, Mercedes Sprinter, Toyota HiAce or a Peugeot Partner. The Sprinter will fit e.g. your plywood, others will have mounts on the side or roof to transport material.

They won't act as a large wheelbarrow though, not well at least.
