Full timing... with kids... Do I dare?

IMO, children need to have roots in one place. Dragging them around the country might be good for you, but put yourself in their shoes. I can make a list of stuff they would be missing out on growing up, and being separated from their peers may cause other issues. What about extended family?

I think your being selfish. Again - IMO only. You do what you think is best, but you asked...
