If you were to Google Death Valley camping or 4 wheeling..searches like that, you'll find just a bunch of info on where to boondock. There are restrictions...like you have to 2 miles from any road. You can't just plunk yourself down where-ever. And, some of the places are really remote and require a lot of planning and even ensuring there is more than just one vehicle.
Death Valley is a very cool place and the history is amazing. Get some books or troll thru Google. The people that used to inhabit the area were crazy tough. And I don't mean Charley Manson, although, you can drive in and see his ranch. That's one of the places you have to plan for.
And check out Darwin on the west side of DV.
