My recollection is that the 2019 HDs (as already mentioned, refreshed, not a completely new chassis) will be introduced at NAIAS in Detroit in January, with first deliveries scheduled for March/April. You know they won't be early, or even on-time, with initial deliveries - it's almost a certainty they'll be late. Not sure when it makes sense for them to open up ordering to customer orders. I guess if you're a large fleet customer that has an established rapport with Ram, maybe you'd get to be one of the first to place a customer order. But individual customer orders, that's got to be a ways down the line.
