I made a quick snippet of pics and vids.

Drove it from Arkansas to Silverton CO, wheeled Blackbear, and some others there in CO including Poughkeepsie Gulch, then to Salt Lake City UT, then to Lake Tahoe CA. Wheeled the Rubicon, then Fordyce, and finally Barret Lake.

The Jeep is amazing. Far more capable than I am for sure. Made it through first 4 winch hills no problem... had a slight mishap on #5... Set it back on it's wheels and drove 3 hours to the other side of the mountain to wheel Barret Lake.

What a trip! Looks like a great time.
 
Maybe this is something everyone else knew... I didn't.

False caster measurement & Fix:
Problem - When I set my caster I set my digital angle finder on top of the ball joint, and pointed the side laser to the same "spot" on the rear axle because I noticed as I turned it, the angle changed. So by pointing the laser at the same relative spot on the rear axle I thought I would be "inline" with the caster angle.

With all my good intentions it was still a bad reading.

I noticed I was fighting steering more than I thought I should so after a little research I checked it from the flat spots next to the diff and the math came out at about 2 degree of caster. I corrected it back to 6 and it drives like a dream now.

Fix - The flat spots on front of the axle on either side of the diff is at zero. It's an easy place to get a good solid reading. The C's are positive 6 degrees from zero.

Figure It might help some other big dummy like me from making the same mistake :cool:

As you turned with the axle on jack stands? Or with tires on ground?
