I as well own a 2016 2500HD, and will say I had that happen very often as I use it for DD, and running my small business. (minimum of 70+ miles/perday) and got to the point where I knew I wasn't going to get an answer (not a stupid 1) from dealer....smh… wish I was given honesty! ya know, the real "im honestly not sure" But, it is what it is.
So, I was lucky enough before all the WW3 gummermant restriction BS, to have my vehicle get a decent "weight reduction" THANK GOD, only problem is moving forward, with more! since I messed up getting just a single without autocal.
