I know that in South Dakota 4-wheelers and even gasoline powered golf carts can be given a motorcycle tag and driven on the highways .... bring that same rig with an SD tag to North Carolina, where those vehicles cannot be licensed for highway use, and you will likely get a ticket

Jim, you did bring up a good point. States are generally reciprocal when it comes to licensing and registration issues however the big exception is for vehicles which are classified by many states as off-road vehicles such as ATV's and golf carts.
