Below are some links to videos of a couple of the climbs.
For those that stated they are worried about scratches, that will a problem. Many of the trails are VERY tight so brush will scratch your vehicle. If you're just worried about dents, then you should be okay for the level-2 trails. Some level-3 trails might hurt a stock jeep (example is the trail called stocker-stopper) but we had some with use that made it through several of the level-3 trails.
As for bypasses, it seemed that some of the obstacles had bypasses and others didn't.
My trail damage tally for the weekend - driver's rear bumper is pushed upward to the point that the bottom of the tailgate rubs the bumper (it's a cheap rugged ridge bumper). My OEM drag ling has a bad balljoint at the axle side now. That's the total on my damage.
My jeep as it was configured for this weekend - 2.5" max travel RK springs, currie control arms (all eight), OME LT shocks, 2 inch bump in the front, 2 in bump in the rear, 35" KM2s running at 14psi on stock 17" rims, front and rear rubicon e-lockers.
I made it up the level-4 section of black mamba -

Also did a level-4/5 on Larry's Hill. This is a video of the fellow behind me while I filmed from the top -

I'll post up some pictures once I make sure I don't post ones that show up as huge.
Oh yeah, last thought - those that had that JK steps (those steps that come on the sports and such) did not fair well, two of them were ripped off. Also, the highway-type tires of the JK sports didn't do so good. Had four tires get cuts in the sidewalls, all of them the highway type tires of the JK sports.
