Did you make your reservations where we talked about? If so, and we are in the water, you call when you get here and we fix you up!
My wife and I are doing the same thing Ron
We've been looking at rv's for months deciding on which way to go. An Etrek with the stand alone capabilities seems like our best bet. Then add a 4wd package and pull a trailer with the mining equipment 
I really like the Sportmobile with Air Lockers also and we are in the same boat with our thinking. The advantage of the etrek is the batteries and being able to stay in the woods indefinitely w/o a generator being needed. It's a tough decision. 4x4 is a must. I was looking at the F-350 and we have a good camper store close by us also and I love the pop ups for going under low branches and through the woods like we do http://www.fourwh.com/ but I've had campers and she really needs bigger to keep her happy.
A nice used lifted 4x4 etrek for the boondocking capabilities with the 16 lithium batteries and solar panels is probably what we will end up with
Kingman sounds great as it is one of the nicest areas in AZ
