Hi Redrocker
Having never travelled this road I cannot comment on that. If I was however doing such a trip, and my wife was not coping with the thought, I would remind her that there will be no mail (hence no bills), no housework (that would not work in my case as I do most of the housework, I love doing it), the peace and quiet of travelling, sunsets away from a town, and a wonderful chance to reflect on happy memories from previous trips.
