I would agree there's no set rhyme or reason. I ordered a powerwagon 9/27, it went D1 11/21 and hasn't budged since. I'm sure its a constant juggling act of parts that are available for options selected as well as lower run trims like mine on top of the fact I went with Hydro blue which isn't a high volume color. At this point, I'm assuming that having a truck ordered in Sept by March (6 mos) is probably overly optimistic. Oh well. More time to gather cash for a bigger down payment I guess.Yea I don’t believe there is any formula to how trucks are being built. Once you get your order in and confirmed, it’s up to the Mighty Ram Gods to decide when your truck will be built and ultimately shipped. My order was placed Sept. 15th and things just started moving for me this month. Finally!!!
