I have not watched the movie but read reviews - they fictionalized and combined different aspects to make it filmable. The real writer embedded herself in vanlife for years and met a lot of different people across the USA who were living vanlife for one reason or another, so instead of focusing on one person's life per the movie as I understand it, the book spends time with different people for months, the audiobook was about ten hours with people and background stories about people and situations which might give a more comprehensive overview of what was happening at that time and now.
