It might not have one on it but the best thing to do is ask a Dodge dealer because auto parts stores sometimes give you false information. For example I own a 99 Impreza with a 2.2 boxer engine and I wanted to chage my PCV so I went to Auto Zone bought one but couldn't find it on my car so I called a Subaru dealer and they said my car does not have one so I know first hand that your truck might not have one but don't go by what auto parts stores tell you because you could be looking for days for nothing.
