I've done it, but in the reverse direction, from the Pacific Ocean in Oregon to Utah. Early in the season bring a chainsaw or have a winch on your Jeep, we had to clear a few tress that had fallen across the trail when we went. Also, some of the bushes are real close together, be prepared for some scratches as you go through some narrow spots. It's a great trip, spend some time on it, it's worth it.
