Jage - Sorry about the late reply, I've been travelling. Apache San Dunes are East of Roswell, while White sands is west, and you can drive on the Apache Sands while you're restricted from White sands. I have been to Lake Meredith, but not to the 4x4 camping areas. It was really nice, and the camp ground we stayed at had great views of the lake. I haven't been to Palo Duro, so I can't help you there.
