I have been thinking about possibly buying a new Diesel Ram in the next year. I have some questions . One thing I have noticed is that they now have an optional 1K torque available. Since it is the same displacement, did they just raise the boost pressure? Is it worth the extra money? How do the new Rams rate in quality and dependability? Anything to avoid? I may, in the future, occasionally rent a fifth wheel, just not sure yet, but I am now retired and after relocation to Idaho, we may decide to travel more and if I am buying a new truck, I want to make sure I get it right. I have owned and towed with gas pickups all my adult life but Texas has nothing like the grades you hit in Montana and Wyoming and while towing a loaded 18 ft. lowboy through there, I got a real wakeup call on the limitations of gas powered trucks. I will buy a 4wd with A/T. I like the looks of the 2500 4 door with a 6.5 ft bed, but have been advised that an 8ft bed gives more trailer clearance when backing up, a 3500 is probably a better choice also, but a friends '17 rides a bit rougher than I expected, so would the 2500 work out for the occaisional towing of a fifth wheel? The other towing duties would be an 18 foot open car trailer and an 18 ft boat. Any advice cheerfully accepted!

Few changes to the new set up.... roller lifters and 10w30 synthetic oil is now the order of the day. While I’m not a fan of the new big screen TV center stack, I see you can still get the smaller infotainment center. 1000lbft.... will only be allowed when possible. Torque management will keep things “safe”. The only eyebrow raiser was the fact that they went to the CP4 high pressure pump. Same pumps that the Duramax guys have been complaining about and failures. I have a truck At work with 7400 miles on it and It needs the entire fuel system replaced due to this. FCA knows and I hear there’s a revised pump or might even be a retrofit kit so they can go back to the CP3 pump. Either way I have a projected date in November for parts. Hopefully the customer plays his buy back card.

The Ram diesel guys were very disappointed they started using the CP4 pump.
I believe the new Ram 1500 Eco Diesels have them too.

I was warned about the CP4 pump when I was Cummins shopping and the serious fuel system damage $$$$$ they do when/if they fail so I stayed away from the 2019 and newer trucks.
Apparently when the CP4's fail it pumps metal shavings throughout the entire fuel system and everything needs replaced.
Some CP4 failures are being denied under warranty and there are class action lawsuits.

I'll bet the higher torque Cummins is only available with the optional Aisen (commercial grade) transmission. As far as 2500 or 3500 that's more of important choice. 2500's have 5 link coil spring rear suspension and a 3500 has leaf springs. You can option for full air suspension in the 2500 or get air boosted suspension with a 3500 (uses both in combination). If you don't like the harsher 3500 leaf spring ride quality for everyday driving I would recommend a 2500 and then add "Airlift" helpers that you can air up as needed for when towing. Then when you are not towing you can have the nicer smoother coil spring ride. Then choose box length. I've seen many people tow a 5th wheel with a 6.5 bed and they have a common tendency to eventually "smack" the cab corner when turning on an unlevel surfaces. Best to go 8ft if you can deal with a long truck.
