My family has always had good luck with Ram/Cummins.
I bought my current Cummins new in 2018, and it’s had no problems. I have 50K miles on it, almost all towing. I’ve never even been aware of a DPF regen occurring. I let it warm up, I allow it to cool down, and I’m slow & deliberate with the accelerator pedal.
I get 13 mpg towing the tritoon, 14 mpg with the horse trailer, and on the rare occasion the truck is unloaded it’s good for 20 mpg on the highway.
I think modern diesels mostly have problems when people try to drive them like a Miata to and from the local grocery store, with no warm up, no cool down, rapid RPM changes, and no sustained load. The Cummins was designed for industrial & marine applications, so I drive it like an industrial engine. It’s been fantastic.
My beat around, burnout doing, grocery getting truck is a beater Ram 1500 with a 5.2 V8 and a 5-speed.
I get my wiggles out with the beater.
If I couldn’t choose a Cummins Ram for towing, then my second choice would be the Ford. They still retain a proper front axle look marginally better than the Ram.
