I did one of these with a freaking generator mounted on the front. The generator bit was a PITA, but the job's pretty easy after you get the intake off. I vote grill.

Also, only god knows what kind of squeaks/rattles you'll get pulling the body off of this beast. They aren't very friendly vans to work on to start with; keep it simple.
