It's worth mentioning again that our rig is titled and registered in South Dakota. South Dakota is unique in that it allows vehicles to be registered in the state by simply having a mailing address in South Dakota. If you've ever visited Mexico, Baja in particular, and wondered why so many South Dakota vehicles seem to visit Mexico this is the reason. Cars, pickups and RVs don't have to return to SD for annual inspections or in-person registration renewals. There are numerous mailbox services in the state of SD that can be used to setup your address that can then be used for vehicle titling and registration. In addition, for long-term travelers such as ourselves with no permanent home in the U.S., SD will issue a driver's license to you using your mailbox address.
Our rig can be sold to anybody in the U.S. and no sales tax would be due for registration if you simply setup and pay for a SD address using a mailbox service. I'd be happy to recommend the service we use if somebody needs it.
