The advantage of getting the SD domicile set up early is that you will have an address for your mail set up before you hit the road and can get that added to credit cards, bank accounts, business cards etc when you have lots of time and the facilities to do it. You don't have to change driver licenses, titles etc until you are ready to fo so. You can get some bills etc sent to the SD address ahead of time so you can show them as "Proof" of your address should anyone require it.
We had it all set up 6 months before we left just so we were comfortable with it all,
If you use the SKP mailing service for SD domecile you will end up with 2 addresses. One for SD and a mailing address in Livingston. Sounds complicated but after 2 years of using it we don't even notice it anymore.
