Glad to hear you are Ok, man. That could have easily ended in a fatality. Scares me just thinking about it.
I got into a bit of an incident with my KJ yesterday, but nothing as serious as that. Some woman in an XJ decided against using her brakes, and smacked into me. I looked in my rearview and saw her coming. She tried to swerve right, and I jumped left (as much as I could w/o going into oncoming), but it wasn't enough. She cliped me pretty good in the rear passenger side. I pulled over, and got out, and she did as well. Luckily neither of us were hurt. I saw the front end of her XJ- headlight gone, parking light gone, maybe some damage on the drivers fender, but the bumper looked ok. I expected to see a bit of the same on my KJ, but nothing. A couple of scratches, but that looks to be it. All of the lines were the panels meet up look ok to the naked eye, and the tailgate seems fine.. Now I know I was driving the superior vehicle

(flame on), but I'm surprized to see no damage.
I suppose there could be some damage under the plastic, and I made sure to file a report at the scene just in case, but it seems ok. Do any of you have any sugestions on what I should look for if I go under the vehicle?
