6.4 Dodge???

I know this has probably been posted a hundred times, but I am looking for some reviews/ real life experiences with the 6.4 Dodge motor.

I currently have a 2007 GMC 2500 6.0 gas in my landscaping/camping hauling fleet. I am looking to add another truck this time around, but thinking about trying out a Dodge 3500 with 6.4.

OP, my good friend and camping buddy had a 2015 Ram 2500 with the 6.4. He liked the power around town and most of the time towing. We tend to tow and camp in the mountains of central/western PA and my friend found that he didn't enjoy towing with the 6.4 in the elevations. As others have mentioned, the gearing is a bit wonky and the truck likes to skip over 3rd gear and downshift into 2nd when you start pulling grades. After 2 years of that, he recently traded it in on a 2017 Cummins.

Meanwhile, my father-in-law tows with a 2011 Chevy 2500 with the 6.0 gas engine. Mileage isn't very good (around 7 towing an 8500 lbs camper), but he has never once complained about power towing the same mountains as my friend and I. While the 6.0 is an older design... GM got it right and made a very good engine. Personally, I would stick with the 6.0 GM engine over the 6.4 Ram engine until Ram gets a "better" transmission underneath that truck.

Now, in terms of maintenance, the 6.4 was pretty easy to work on. Oil changes are normal, there is no "mystery oil" like Fishie would have you believe. I think my friend bought his oil at Walmart or Tractor Supply. It is certainly available across the country for a reasonable cost. Twice as many spark plugs has twice the parts cost at replacement time... $120 instead of $60 every 100,000 miles. It would be laughable for most people to complain about that... for Fishie its just another in a long line of outlandish complaints about anything Ram related...
