Sorry I missed this thread. My son and I hit the trails in his 08 JKU along with my son's friend in a FJ Cruiser. This was my first venture on the trails and it rocked. I drove some trails Friday night and Saturday in the soup. We couldn't make it up Dutch John Saturday, but my son made it up Dickey Bell Friday night; no lockers.
We also talked to a guy in a Hummer H3 that had Dynatrac axles front and rear. He said he lived close to Dynatrac in CA a while ago and they were experimenting with getting all the electronics worked out. Not sure what year he had them put on but the rig was awesome looking.
