A couple years ago, my buddy and I had just finished enough of his SAS project on the hundie that we needed a test drive. This trail is relatively close and has some great views. We managed to rope our other friend (who owns the orange FJC) into it as well.
Nothing failed and all the welds stayed welded, so that was nice.
Its a neat rig and its surprised me a few times by just rolling over stuff. A guy named Ken runs a youtube channel called OffroadHub. He's basically built an FJC about as big as reasonably possible. Kinda nuts what they can do.
