I'm relatively in the same boat as you, having recently started looking into Diesels again, but being very gun shy as I own a 2004 F250 KR which came a leftover 2003 6.0. Quite possibly the worst engine ever put into a truck in history IMHO. Some will say they they are great engines, mine has not been from the day I drove if home from the dealer it started having issues and to this day, remains problem ridden. I also own (company truck) a '14 F350 6.7 and it has been relatively OK, but currently has intermittent check engine lights depending on which way the wind is blowing that day. When the 17's came out, I looked pretty hard at 'em but ultimately decided to pass just to see what kinds of issues owners would have. Several years go by, and it's the same old story, unreliable engines plagued with issues mostly due to emissions crap. Chevy's are no better, nor are Rams, nor are GMC's, nor is anything for that matter, they all have problems. I also own 2 Mercedes Diesels, and they are head and shoulders better engines than anything American made, you just can't get 1 in a truck that can tow anything substantial. Personnally, I'm prolly going back to gas engines in a Superduty or Ram... I don't have to drive a truck everyday so can keep the mileage down, and hope to get lucky for a change. Years ago, I swapped a 1996 EFI 460 Ford and E4OD trans into an 89 Bronco including a full harness swap, transfer case adapter, etc. and it was bulletproof for years and years, and I beat the hell out of it offroading. The only repairs it had in all those years was a Tranny Temp Sender, an Ignition Switch, and a pair of Bosche AGM Batts... Other than that, it ran like a clock and never left me stranded... I'm done with American made diesels...
