I was finally able to make it to Jeep Beach this year. It was a ton of fun and I wish I had been able to make it in years past.
The TJ absolutely ate up all the obstacles, including the "wall." The rock garden was a little tricky and put a few marks on the undercarriage.
On the rightmost rock garden the exit was a 18" pillar which got my front LCA mounts the first time and the driveshaft the second time.
It put a good sized dent in the driveshaft. I was able to keep playing that day but had to tie it up for the trip back home because it gave me a pretty good vibration above 40.
Here's a video of said driveshaft damage:
In the next couple of days I'll be able to throw together some video clips I took.
