Nope!! NO SALES TAX on the motor home itself when I bought it....nor the toad, nor any of my other major purchases since I moved here in 1993.
Plus, my car registration used to be under $40 for every two years when we first got up here, but that has been creeping up and it is almost $90 for two years now... These fees are independent of age or value of the vehicle -- quite a change from the California taxes & registration we were subjected to prior to moving here.
