It always sucks to get hit. It is good that the woman left her info even if there was no damage. If a kid hit you they probably would have left and you'd be wondering why there were plastic pieces on the ground behind your truck.

I also like having a lifted truck as it gets the body somewhat out of harms way and my hitch has also protected my bed when I've been rear-ended. The hitch does make a nice radiator destroyer and leaves the other car with far worse damage.

I would take the truck in to a body shop and have them check it out just to make sure any hidden damage is discovered. They may find that the hitch should be replaced and then you can decide what to do with it.
