Are most national forests and BLM lands normal car accessible? And are they RV accessible? (Is there a place to park?) If so, will this get you more easily discovered (I do NOT intend to camp in the car)? Actually though - is it reasonable to camp in a car on National Forest or BLM land? If having a car there will get me more easily discovered or if there is not a good place for long-term (or at least a week or two) vehicle storage at/near a National Forest/BLM area, then where would I keep my vehicle?
