I've owned my 2012 Ram w/ Cummins since it had 24k miles on it in late 2013. Since then I've done all of the maintenance myself expect the EGR cleaning (dealer did that)
I replace my fuel filter / fuel water separator every 10k miles and drain it about once a month.
Do most of you have your fuel filters changed? I was talking to a group of Diesel truck owners over the weekend at a camp ground and none of the 8 of them ever heard of changing fuel filter, or draining the fuel water separator.
