Passenger vans and cargo vans differ primarily in what their interiors are equipped to carry. A passenger configuration provides designated rear seating and the associated restraints, access, and cabin equipment. A cargo configuration devotes more of the rear space to goods, with equipment selected for loading, storage, and restraint of that load.
They may share a vehicle platform, engines, or exterior panels, but shared appearance does not establish identical seats, floor attachments, glazing, climate equipment, airbags, or load capacity. Compare the exact model year and configuration before treating parts or interior layouts as interchangeable.
