It varies by the motor vehicle manufacture, but they generally stop taking orders for the current year in July or August.
Do you think it might be earlier this year with the new body style after the break?
I wonder if you could even find a dealer to order anything right now, with the excess inventory? I have yet to see a new body style 1500 around here on the road, BUT have seen a few sitting at the dealer, sales are pretty slow, at least in these parts.
