Does anyone know how long you might have to make a change to a truck order? I placed my truck order a 1 1/2 weeks ago and would like to add the park assist option (a friend talked me into it). I called the dealer and was told the truck was in "D" status and could not be changed. I don't want to delay my order but I would be a bit surprised if Dodge would not be able add this option this soon after I placed my order. Great forum, thanks for your help.
