Living out of a motorcoach good for the kids, and maybe the whole family or not?

If parents decide to pack the family in a motorcoach and live out of that while traveling America would that be a good or bad experience for the children overall or would it come down to the ages of the children? Aside of the obvious hard to make and keep friends thing and the lack of space and privacy what are some of the other cons you can think of as well as the pros? Do you see more cons than pros or the other way around?
