Just to clarify my original question, we are paying cash (no loan) for our RV and will be full-timing (we have sold our home). We would domicile in SD, not physically reside there.
The only issue I imagine is if we were ever pulled over in SD, would it matter that we have SD drivers license and MT plates? Otherwise, I would not imagine any other issue if we were in any other state.
