Just to give some insight into how we do these trips mostly on dirt/find these spots, obviously the internet is no use and even Garmins off road maps don't have a lot of logging roads/forest roads, these Vehicle Use Maps are what we rely on most of the trip. Each ranger district in National Forests, or BLM/National Monument offices normally have one for their district. We call ahead and ask them to leave one outside if we're going through on the weekend/afterhours. There's no guarantee the roads are negotiable though, you'll regularly find roads that haven't been driven in years for better or for worse. If you're looking to never stay in a campground these maps are a good place to start.
