I use the Escapees mail service and their South Dakota address and it really is no problem. You use the SD address for your drivers liscense, registration, auto and health insurance. Everything else goes to TX. Everything that goes to SD is forwarded to TX in a day or two. There are many SD mail forwarding services to use if you don't like this 2 address system. I used Americas Mail Box (AMB) for one year before I joined Escapees. I have heard of others like Dakota Post but know nothing about them. I met a gentalman at Quartzsite that was promoting a mail forwarding service out ofHill City SD but I can't remember the name of the company. You can change your address now via telephone,they will take your credit card and set up a box # for you. When you get to SD you go to DMV, any DMV doesn't have to be in the same city as your address, and show proof of at least one overnight stay at a hotel or RV park, AMB has their own campground. You don't need any mail to get a drivers liscense just proof of one night stay.
