Dodge does "funky" things with thier website. In certain areas ( zip code info ) they will block out certain options. At the end of a run it seems they will block out the oversold options. You need a good dealer with the REAL DEAL ordering website to see what is actually buildable. - Look up tommygun. As long as it is not a unit for the communist states of CA, MA, CT, RI you will be fine ( need border states emission CERT label- same truck).
