Interesting movie, but the bathroom arrangements were not ideal, you had to get rid of your own waste.
We became 'grey nomads' in 2009 and took 12 months to tour right around Australia. We had our own shower, toilet and washing machine plus air conditioning in the van which made life fairly comfortable. Just like the movie, met some great people and had some good times. Met a couple who had sold their home to become permanent nomads but while their van was depreciating in value, their home (that was sold) was increasing in value. I felt bad for them, they were both around 60 years old and were heading into old age without any anchor (home) in case things got rough.
If you look at the pic above, actress Frances McDormand went to a lot of trouble, knowing she was nominated for an oscar (not), no hairdresser and no make-up, I love this woman.
