I have 5160s but close enough.
Bring a trailer if you can. You never know who wont make it.
Make sure your winch is in good working order.
Have basic tools.
Prepare for a long day - lots of water.
Small group will make it easier as the day will be long enough as is.
Make sure bump stops and limit straps are in place. That trail will flex you out.
All good advice! Every time we have been there, jeeps have carnage. Most frequently, axles, shocks, mounts, wheels and tires, body damage.
Bring some ratchet straps. They can be useful for holding an axle on (if a mount cracks) or for holding an axle housing to the frame to make the jeep easier to jack up should you have to pull an axle.
