If it is near the highway I just make sure to park where the passing headlights don't illuminate me. Heck, turnouts with big off pavement areas on lesser traveled two lane roads can be just fine. Once I get out onto the dirt roads I'm looking for views, streams to fish, anyplace away from everyone else and if all else fails anything somewhat flat and out of the way
This was just a large pull out on the side of Hwy 88 that I slept in when I got too tired to drive

it had a great view at sunrise

down a dirt road on the Carson river

just go for it
