re: OT sell me on this truck. Update #2

Idk about the gasser, but I have a 2021 Ram 3500 dually with the Cummins, I average 18.5 mpg with a cold air intake being the only upgrade. I have actually seen 21.8 mpg before. It’s the rear end that mainly affects the mpg when not towing. I have the 3.73’s, it’s the 4.11’s that give a lower mpg. The def is negligible if you go to a pump (2.99 per gallon) and not buy tbe 2.5 gallon box for $18 at a store.

Maintenance can get expensive. I used to pay $225 per oil change, but I change it now for $100 and change my own fuel filters at $40. To which I do religiously.

The tranny and the front end iare the weak links. The 68RFE makes me nervous, but with 126k no issues at all. Though it is my daily driver, I also pull a 5th wheel, a 20’ utility trailer w/ tractor, a 14’ enclosed cargo trailer and a 20’ cattle trailer all with no issues. My mpg towing has averaged 12.5 mpg.

The front end is a solid axle, and therefore can not be aligned like a normal truck. I would suggest changing out the oem ball joints to a high quality adjustable ball joints so that your front end can be properly aligned and not eat through tires.

Even after all of this I would never go back to a gasser, I love my diesel. If diesel is too expensive, get the upside app you can save a lot. I have saved $1100 across 2 years. Which is roughly 2 months of diesel for me.
