* Wheelbase: Longer wheelbases generally mean heavier vans.
* Engine: Different engines have different weights.
* Payload Package: Vans with higher payload capacities will naturally weigh more.
* Options: Added features like power options, extra seating, and specialized equipment all add weight.
Therefore, there's no single answer. You'll need to consult the original sticker (monroney) on the van itself, or look up the specifications for the *exact* configuration of the van (engine, wheelbase, etc.) in a source like a Ford owner's manual or a vehicle specifications database. Even then, that weight will be the *GVWR* (Gross Vehicle Weight Rating), which is the maximum allowable weight including the van, passengers, cargo, and fluids. The *curb weight* (weight of the van without passengers or cargo) will be lower.
