Car registration during short tour

Not sure if this is the right sub but I figured some people here would have insight.

I’m going on a short tour and my wife and kids are living with family in PA, but not the state of our last duty station (FL). Our car is registered in FL. We won’t be going back to FL after my short tour and so we no longer have an address there. How should we handle the car registration and my wife’s drivers license? We do have mail forwarding set up so theoretically if anything regarding the car is sent to our old address, they’ll get it at their new address.
