Yes, that was the inner wheel well in the back seat along with the fender flare. I had stepped the driver's tire up on a rock and didn't see the stump on the other side. With the low clearance (stock height minus armor weight), I couldn't straddle the rock like everyone else in their TJs. The stump caught the bottom of the bumper (air dam?) and shoved it into the tire, the tire then went to rip off the bumper and everything attached. Luckily, we were able to salvage the bumper from too much damage and only had to reattach the fender flare/inner wheel well. It just so happened that when we went to back out of the trouble, another part of the stump caught the inside of the bumper and wanted to rip it the other way. Lose lose situation.
I apologize for not having more pictures of the XK in action, but the wife was riding most of the time and I haven't seen anybody in our group post pictures. I don't think they got any of the XK, and we were lucky to get the few we can.
Rocky Road said they would send me a new Superslider after returning this one to them. The clip from their e-mail back to me: "No problem. Just return it, or bring it in, and we will send out a new replacement for you." The only problem right now is figuring out how to send it back. UPS wants it in a box, but they can make a box for it. The downside, it'll cost about $40 more to send it than it did for RR to send both of them to me shrink wrapped. At the size of the package, UPS charge based on dimensions, not weight
I'll have to see what Fed Ex can do, or suck it up and spend the $120+ to send it back to Utah from Virginia.
Carnage: some paint on the bottom of the fender flare rubbed off, and the rock slider was bent. The fender flare is snapped back in now, but not as secure as it was. Those plastic rivets and clips are mighty expensive ($6 apiece), and I still don't know the best way of installing the rivets.
The Pontiac Solstice that has the rock under it, well, we left before it left. Our guess is that the rock was put there after the car was parked. A cruel joke indeed, but why is a Solstice and a Mini Cooper in the parking lot?
I think I have answered everyones questions and responded to about everyone in this post. If I missed something, let me know.
Karl's formula for the fun hits the nail on the head. However, your heart pounds after hearing the crunch of the bumper and clips popping, and it pounds for a good hour or so.
