Well I guess I should update. Moab was great, but way too short for the money it costs to go out there. Next year I'm definitely staying for the entire EJS.
The group I was with decided to run Pritchett Canyon on saturday and I very shortly had an issue upon hitting the trail. My driver side hub didn't seem to want to engage properly. I quickly took the cap off and everything inside seemed to slide in and out properly. The spring inside the cap seemed a bit week so I swapped it with a spare and success, true 4wd.
We then continued up the trail until my neighbor stopped to check things out. For some reason his ARB's weren't engaging. We started looking things over and after some time realised that after 10yrs of use his compressor had finally bit the bullet. The "crank shaft" end had broken off of the motor shaft. He then turned around and headed into town to resolve the issue.
We then came to the first big off camber climb (I believe its called "Which Way"). As I was turning to approach the obstacle I popped a bead on the passenger side front tire. A little ratchet strap and ARB compressor action and the issue was resolved. However, because of this I decided to run higher air pressure (14psi) and this would cause other issues throughout the trail with traction. After the tire issue was resolved and we waited for an XJ to work its way down I made it up the obstacle with little issue.
I made it through "The Tube" and "Damen's Hot Tub" no problem and finally we got to Rocker Knocker. I had been watching YouTube videos of the line up it for a week and after watching the first of our rigs make it I gave it a shot. Much to my amazement I made it first time, it was awesome.
I then made it over Suicide Hill, this took a little bit of effort. Everytime I started to get up onto the hill at the bottom I would lose grip and the Jeep would start bouncing. After I got up and over that first ledge though it was all gravy.
Rockpile on the other hand...............

After we got the Jeep back on its tires we decided to turn around and head back to the bottom of the trail. Unfortunately for me right after I made it down Suicide Hill my fuel pump decided it had had enough. We dragged the Jeep back over to Rocker Knocker and then hauled back into town. I missed O'Rileys by 10 minutes and we headed back that morning to replace the pump.
Overall the Jeep did well and I was really happy with the results of my first trail run in the newly assembled rig. The fuel pump was just crap luck, you can't really lan for that. It was the stock pump that came in the Jeep when I got it and I had hardly driven the thing in the last 1.5yrs I've owned it.
I definitely need beadlocks. The rims being 9" wide just don't provide that "poor-man's beadlock" effect that my 15x8's did when I was running 36x13.5 Iroks. Those I would go as low as 4psi and never pop a bead.
My super awesome square driveshaft caused issues. Where I had designed my belly pan to go up and over the driveshaft was to close and when coming down obstacles the shaft would hit it. I had designed it using a stock driveshaft to check for clearances (1.75" OD), and the 2.5" square tubing just didn't have room. I actually popped a front u-joint coming back down Which Way after getting the pump issue resolved. Since coming home I've sourced and stretched a stock YJ front shaft and it has plenty of room, I used my winch to suck the front suspension down until the axle was nearly against the frame and no binding.
Those little wraps around the leafsprings are important but hard to come by. I found 1 and have temporarily used hose clamps for the remaining springs. I had some issues with the leaves wanting to slide out of alignment.
But in the end my biggest issue was myself. I pretty much always had a relatively under geared and small tired rig and relied a lot on throttle and prayers to get over things. With the massive amount of gearing I have now its too easy to over throttle and get way too much wheel spin. I've got a major learning curve with this rig but its definitely nice to finally be able to wheel it. Oh yeah, and your front ARB doesnt do you an good if you forget to turn it on.

I'll get the pics from my neighbor and then post them up.
