RV Sales Tax - Deductible - AZ?

 In 2012 we purchased an RV and paid about $2500 in sales tax (we financed the RV).  I have searched all over and can not find a definitive answer.  Is this tax deductible??  The purchase was made in AZ.

Thank you for the help!
    You can deduct sales tax on a new or used purchased or leased vehicle or boat but, if you live in a state with a state income tax, it probably isn't to your advantage to do so.  To claim sales taxes on a vehicle or boat you need to meet two criteria.  You must itemize deductions, and your sales tax deduction, including the sales tax on the vehicle must exceed your state income tax.

    Realistically, in most states with a state income tax, the state income taxes would be higher than the state sales taxes, even with sales tax on a car added.

    If you claim the standard deduction, you cannot deduct sales taxes.

    The deduction for sales tax is under the deductions and credits tab.  Go to: Deductions and Credits > Estimates and Other Taxes Paid > Sales Tax.

    Click Update next to Sales Tax.

      People come to TurboTax AnswerXchange for help and answers—we want to let them know that we're here to listen and share our knowledge. We do that with the style and format of our responses. Here are five guidelines:

      1. Keep it conversational. When answering questions, write like you speak. Imagine you're explaining something to a trusted friend, using simple, everyday language. Avoid jargon and technical terms when possible. When no other word will do, explain technical terms in plain English.
      2. Be clear and state the answer right up front. Ask yourself what specific information the person really needs and then provide it. Stick to the topic and avoid unnecessary details. Break information down into a numbered or bulleted list and highlight the most important details in bold.
      3. Be concise. Aim for no more than two short sentences in a paragraph, and try to keep paragraphs to two lines. A wall of text can look intimidating and many won't read it, so break it up. It's okay to link to other resources for more details, but avoid giving answers that contain little more than a link.
      4. Be a good listener. When people post very general questions, take a second to try to understand what they're really looking for. Then, provide a response that guides them to the best possible outcome.
      5. Be encouraging and positive. Look for ways to eliminate uncertainty by anticipating people's concerns. Make it apparent that we really like helping them achieve positive outcomes.
