Yes, going out to the south is better, as that is the direction towards the Grand Canyon. I did just expand my horizons on Google Earth, and there is a big mining operation out there, just don't know how much is private or public lands in the area. I will order an AZ. Strip map. There does seem to be quite a few dry camp areas a little further south of the 15 exit big turn out, and they are away from the main road going to the mine, so dust shouldn't be an issue. I think in my mind, I wanted to know how far anyone had gone south pulling a trailer or in a MH towards the Grand Canyon, and if it was feasable. We intend to be there a week or 2.
