I current have a Hemi. Purchasing a new truck and debating on getting the Cummins. How is the quality of the Ram 2500 Cummins? What should someone know before moving from a Hemi to a Cummins.
Thanks in advance!

So, I have one foot in both camps as I want the Diesel and will be pulling a 4 place covered snowmobile trailer for 8 hour trips one way several times a year. It would be my daily driver, 20 min commute. I like that they last forever, and hold their value better than the Hemi. How much is the def fluid and how often do you have to fill it?I know you just asked about the quality of the new modern day Cummins turbo diesel‘s but, there any particular reason why you’re wanting to move up to a three-quarter ton with a Cummins?

Gotcha - thanks for the correction@John Jensen I was not referring to intake air filtration. It's air in the fuel that's the issue. It causes pump cavitation.

However, I've not heard of that problem either. I read a lot where guys are afraid the capless fuel filler will allow dirt but not aware of air in the fuel.
Could you elaborate and also comment on what the preventive mods might be.
Thanks
Yep, helps a lot. ThanksHow do you know if you have water or air in your fuel system? If it is a diesel then white smoke and rough running is one of the symptoms of air in the injector lines. The engine may start and run briefly, then stall and not start. Water in the fuel tank/line will cause the same effect.
You can purge the injector & fuel lines and there's a documented process for that.
But how in the heck does air and water get into the fuel in the first place? Water, well, it's a thing and it's an easy thing to have happen depending on your fuel source, storage tank condition or even if you don't seal your fuel neck. Most newer diesel trucks have no cap on the fuel filler neck. You'll find the same omission on the DEF fill. So water happens.
The capless systems are not supposed to suck air or be a water infiltration location but I have my doubts that the little metal flapper in the neck will work properly for the entire life of the truck. Sealing the filler necks has two benefits. 1) No water or air can be introduced into the tank, and, 2) no low-life creep can pour anything into either of those openings.
Air in the fuel is also a thing but it indicates that some issue exists in the fuel system. Air bubbles are caused by any air leak on the vacuum (suc‑ tion) side of the fuel system from the fuel tank pick‑up to, and including the lift pump. You can also introduce air into your fuel system if you run the tank too low and the pump starts to cavitate, sucking air into the lines.
So when it's air the purge method is used as well as a fuel system pressure test to find any air leaks.
The water fix? Fuel treatment systems to remove air and water from fuel have been used for years on large diesel powered trucks for years. The technology is available for light duty trucks as well. Companies like Ingersoll Rand, FASS, and others have systems available. Another method is treating the fuel with additives such as those produced by Bell Performance and many others.
I hope that helps.

You hear this argument a lot, but you have to remember that the truck is also worth a lot more when you sell it.I would also add higher initial cost. The 6.7 Cummins option adds around $10K to the sticker price.
Agreed.It seems the Cummins option buyers fall into 2 camps; those need it for hauling and those that just want / like a diesel engine. The first camp is practical and the second camp is emotional. It is pretty easy to determine load, frequency, typical terrain, etc to make the practical decision. The emotional one, I won't go there ....
