Well, after 17 years and 360,000 miles of very strong use out of the Beast in my signature, I finally am breaking down and getting a New (2018 - on order) vehicle!! I get to join the the 'new' crowd. So - who has any gotcha's list regarding the 2017 and up 6.7's? Thanks ahead of time. I will be cruising the forum for a while as I learn the new vehicle (it has been since 2010 since I last posted ). I have been hauling a Sundowner 2-horse bumper-pull pretty regularly with the Beast and now have an 8-horse gooseneck Sundowner to use as well.
