So far we have more than 15 stops.
Let's see if I can remember them -- Canberra > Sydney > San Francisco > Los Angeles > Denver > Dallas (for an hour) > Omaha > Dallas (for a stay) > Lexington, Kentucky > Chicago (we go there by car and maybe have a side trip to Madison, Wisconsin) > London (for a few hours) > Amsterdam (with a side trip by train to Belgium) > Madrid > then we work our way to the south of Spain to meet the truck in Gibraltar.
About 10 months later, we surface in Istanbul. The trip home is Istanbul > London (probably with a stay) > somewhere in Asia > Sydney > Canberra.
Oh, dear, I just thought of a change I'd like to make. Back later.
