I am on the fence and baffled as well. We had a man go missing this year a few houses down from me. He walked into an area that is 90% large open fields with vegetation no higher than a few inches...and it took 2 days to find his body lying down right in the middle of one of them. He was less than 2000 feet from his house. She should have been out of his sight for 5-10 minutes but she was actually out of his sight for many hours by the time LE arrived- If she had been close to the RV initially, but lost, she had hours and hours to get much further away as he was looking for her. Most lost people are found within 1-2 miles of where they were last seen but some, even children, have walked 20 miles overnight. Not that I think she made it 20 miles in that heat, it's just an extreme example of what has happened in the past.
