Wish I could help. Live in Chino Valley and just took delivery of a new 5th wheel. Had the dealer do the MVD stuff, but the invoice shows $495.73 for Title, Registration, and License for two years. There was some credit on the Tags on the trade in, so it would be slightly higher that the above.
Also the value of the RV will have a bearing on the "tax" portion of the Tags.
