Trailer Hitch/Rear Bumper Caravan

I have an '03 Grand Caravan. I need to install a trailer hitch for this Summer's camping trip. One of the four bolts is broken off and I
need to pull the bumper (inside the plastic cover) to get the broken piece out.
Simple question: Does the bumper cover have any "hidden" fasteners. I found three screws on the inner wheel wells, two more on the left and right sides of the cover exposed when the liftgate is open, and four or five plastic body fasteners underneath. Have I found everything?
