I have a 2013, 5.7 with 456 rear end, amazing what that little motor will pull, hay trailer, stock trailers, always something hooked up. I take this truck through stuff on ranch that other trucks would have to be pulled out with a tractor. I know my son’s 2017 With 6.4 with 410 rear end and has been a great truck too, his is at about 150-k miles, mine is only 75-k , I have a 2012 diesel too, and a jeep rubicon, we need these to get in and out of hear in bad weather, I have Ford feed trucks, I know a Ford is made for hard work !!
