i could be wrong, but i understood VIN # is created after they have confirmed the parts are available and before the factory starts building it ( they need to know what they are building) . Until then, they can reference VON#.I am in BC Canada. Your dealer is lying. All they have to do is check the status of the order(if they actually ordered it) and it will tell them the state of the order. As soon as the vin is there they will see it. They should at minimum have a VON by now. I ordered mine on feb 2 and received the truck 2 weeks ago. I got my VIN within a few days of the order being placed.
This is where mine is sitting, waiting to confirm parts are available. i placed mine 05/20 so i dont have much hope
