Holy thread resurrection, Batman!
I've been looking for a Haynes manual for my 2018 since I bought the thing in Oct '17, and I think I just found it on Amazon. But it says not available until June 11, 2019. So I looked at the Haynes website. It was hard to find, but it's there, published last month for 2009-2018 Dodge Pick-ups. The Haynes site book and Amazon book have same ISBN numbers which are different from the 2009-2016 manual.

Their Ts & Cs only allow linking to the home page. To find this manual, click New Products at the top and find the Dodge Full-size V6 & V8 Gas &... picture link.

I'll be the guinea pig and order from Haynes and let you all know if it goes awry. The online preview on the Haynes site is still the '09-'16 version.
Edit: I tried to order on the Haynes website, but the last page would not allow me to accept the Ts & Cs so I had to call them to order it. Got it for the same price, $19.95, with free shipping. Customer service said their website support knows there's an issue and is working on a fix.
