"Bought my 07 5.9 Cummins Bighorn 4x4 in Sept 2018 with 72k miles. It was not cheap! Low miles and the original owner had had every scheduled service done at the dealer so I went for it. My first automatic transmission in 45 years! So far I love this truck! No issues except "death wobble" which is common in straight axle 4x4's, and it was easy to fix."
