This is essential anchoring out. Except with a truck. In the desert.
What's essential here is there are no services available. The BLM interactive web site maps are hard to use.

We have an air mattress for the bed of the truck. A little propane cooker. A folding table and chairs. And a bucket/potty. All the comforts.
I think I want to download some maps. The hard part is having them available off-line. In the olden days, we used to buy paper topo maps. I haven't bought a paper chart in years.
