No clue, I know the use of good oil and frequent oil changes goes along ways, especially with diesels. Like I said, my neighbour is happy with theirs. It would be a bonus if you had the service history for the truck. I was excited when the diesel option first came out, but couldn’t justify the expense for the amount of driving we do. I know the 5.7 Hemi’s have had their own share of issues. I have had a 2012 and now a 2016 Larimie that I am happy with (Hemi). You are correct, do your own research.
