At the GLJT Show and Shine today, someone brought a scale so we could weigh our jeeps, and I got some good info on my XJ today
The weight of my XJ with me in it is: 4115 lbs
It breaks down like this:
front left: 1105 lbs
front right: 900 lbs
rear left: 1163 lbs
rear right: 1100 lbs
This was with an almost full gas tank
