Rick - You might want to try removing the swaybars if you have not already done it. I found it really did not effect road handling much and it has made a huge difference off road. Switching from BFG AT to MT tires has helped a lot too. I'm probably going to wait with the lockers on my truck until after I add an OME lift and put on some SSRs.
Since you are in Dallas, have you thought about joining Texas Rovers (www.texasrovers.org
)? Right now I'm the lone Defender so it would be nice to get another D90 on the trails. We have a meeting next Tuesday the 26th if you are interested. Send me an email or PM next time you want to do some wheeling.
