Here I begin the debate.
We have been legal residents of SD while full timing.
We have now bought a home in AZ.
Can we continue to register our motorhome in South Dakota once we get new drivers' licenses in AZ?
Thanks.
You can continue registering the RV in SD but that would not exempt you from legally being required to register it in AZ. Once you obtained the AZ operators license, you became a resident of the state. As a resident, the ARS require you register all motor vehicles with AZ. There are some exception but wouldn't apply in this case.
As for enforcement, unless pulled over between October through April, odds are LEO's or DOT Enforcement wouldn't be looking for violators (too many snowbirds). But come the "summer" months, DOT is more likely to be out crosschecking registrations and drivers licenses on-the-fly to see if they have a violator.
Just to add; A state may allow you to register a vehicle in that state based on their regulations, but that doesn't mean it negates another state's registration requirements for residents. You may have been reading about the Montana crackdown and that's causing lots of hurt to many when caught.
