there is some lag in production changeover period
There would be some lag when they change over to '18 production from what I have read on this forum...perhaps 60 days if memory serves. The only thing keeping me from sacrificing my deposit and doing an '18 is the absence of AG paint in '18...I really love the color so it may keep me at home so to speak. Not really a lot of upgrades that make any difference for me in the '18 model anyway as the audio thing is immaterial to me. However, the depreciation hit is a decent consideration-- you and I will get a year old truck for all intents and purposes.
