I think you're giving Ford too much credit on the design of these.. Also keep in mind as vans are trucks, they are exempt from many 'passenger car' regulations... not sure if this specifically applies here though.

As far as I know, all the aftermarket front bumpers mount in the exact same place as the stock bumpers.

Certainly possible, but we're talking safety, so more airbag deployment is better than less deployment IMHO.

Again, they all use the frame crush zone, so far as I know.. And the stock Ford bumper doesn't have much space to give, so I think drastic changes are unlikely.

Great discussion everyone. I am learning a lot on this topic and this reinforces me to drive double defensively.

Better safe than sorry.
