We just did that last year. We signed up for mail service with your best address in Sioux Falls. It is not necessary to be a resident to plate and title your vehicles there and the vehicles do not have to be there and inspected. We were given our mailing and resident address and with their assistance we titled and plated our vehicles. We needed to do this because ours were expiring in our home state before we could visit Sioux Falls. In Aug we drove to Sioux Falls, got our drivers licenses , purchased insurance for everything and opened a bank account. By setting up the mail service first, you will have the SD address on mail for getting your drivers license. You need to spend at least 1 night in the county with a receipt that has all names of the parties that want to get drivers licenses. Be aware that Sioux Falls is the only location open on Mondays. We chose Sioux Falls simply because it was much closer to where we were rather than say Rapid City. You can do a google search - mail fowarding services in SD and you will get a list of various ones. After signing paperwork and paying the intitial fees to establish service, you need to change your address on all of your mail to the new SD address so all starts going there. We just request our mail sent when we are stopped somewhere for a few days. Read some of the service websites and you will find additional information. You should change everything over just the same as if you bought a house there and NOT keep things in various states.
