We were truck shopping in July, and by early August we figured out that we wanted the ED. Walked into the showroom, and no orders were being taken. Living in SoCal, we were willing to buy in Las Vegas Nevada, but ran into the same thing. Then got the call back in early September that we could order our truck. So it must be some kind of allotment control thing but not sure. But for us it's worth the wait. Also keep in mind that there's usually a plant closing between Christmas and New Year.
Our truck is slated for mid November, but is currently in 'storage' so don't even know if mid-November will hold. Point is if I had to wait longer for an ED I ABSOLUTELY WOULD! So be patient, because it's the only light duty diesel truck on the market, and when you factor in the coil sprung rear, nice interior and exterior, 8-speed tranny, it becomes a no-brainer!
