40' vans are similar to unibody cars in that the box acts as a significant part of the frame structure. Flatbeds are similar to body-on-frame construction used on pickup trucks.
If you are sold on using a trailer for a bridge, get a flatbed and forget the van.
If you haven't noticed, take a look the next time you see a loaded and unloaded flatbed trailer. When unloaded, you'll see a noticeable arch in the frame, which is there to compensate for the cargo's weight.
