Mobile living is great. (with a family, I don't know...)
I still have my mobile home stuck in the UK, slowly decaying....
In my my younger days - I bought an old merc ambulance, and refitted it (badly), and then spent 7 months touring around Europe.
That was my first taste of mobile living, and I loved it!
Where in France are you heading to?
Am hoping that the addition of the family will only make it a richer adventure ;)
We will be living just outside of Perpignan.
Until the vehicle is acquired...
