Input on 2025 3500 6.4L

Bull Creek said:
We own both a Ram 2500 4x4 Tradesman Power Wagon with 4.10-1 and a Ram 3500 4x4 Tradesman 6.7L with 3.73-1. At our high elevation local driving (10,500 feet) the turbo diesel is a rocket versus the gas. No comparison.

This was a factor for me getting the oil burner. My 2500 with the 6.4 would dog out on the high altitude passes but the 6.7 doesn't give two chits about it. I had the 6spd transmission so that was a factor, but you could tell the motor was starving for air.

2500ft above sea level here so should be fine. Hoping this 6.4 is gunna be the last truck I buy for awhile. I’ll be staying on top of the oil changes for sure always do!
 
I have the Rambox bed.

Gross truck: 10,000lbs
Truck empty weight as driven: 7,420lbs
  • Front axle 4140 lbs
  • Rear 3280 lbs
Max payload: 2,822lbs (per the sticker) vs what it scales with me and tools etc reduces the payload to about 2,580lbs.

Payload on our 2024 Ram 3500 Crew Cab 4x4 Tradesman 6.7L is 4,074 lbs per the sticker versus 1,446 lbs on our 2016 Ram 2500 Crew Cab 4x4 Tradesman 6.4L. The 2024 has the Snow Plow Prep package and the 2016 has the Power Wagon package. Not much else as options which keeps the payload sticker maximum pounds higher.

He meant less weight then the Diesel.

Yes, a gas is less weight empty than of the 12,300 lbs gross of our diesel. Don't have the empty weight, but subtracting its 4,074 payload may be close. 6,000 lbs gross front axle and 7,000 lbs gross rear axle.
 
Many issues brought up on this thread have been going through my mind, over the past month.

1. I have a 2006 Dodge 2500 4x4 5.9 Diesel. It only has 190,000 miles on it, and I still love this truck.
I rarely drive it, but I when I do, little things are seen that need addressing.
I need the drivers, and front passenger seats worked on(adjustments acting up).
The tranny is original, and will need rebuilding before I retire in a couple of years, and start pulling a heavy travel trailer.
I recently upgraded my injectors, but the Injector pump will probably need replacing, before the retirement.
The A/C system is flakey, and has a very slow leak.
2. I If I buy a new Ram 2500 w/6.4 Hemi, my mileage will suck, and suck bad. I like the mountains, and pulling in the mountains with a gas engine, well it feels anemic. HEMI TIC. Have they solved this yet? I haven't heard that they have.
But, my drives are usually short when not on vacation, and the gas engine will be better than the newer diesel engine.
3. Getting the 2025 Ram 2500 Diesel will be effortless, when pulling a trailer. But, since I will be driving short trips, when not pulling on vacations, it will be parked. My other vehicles will have to be used for daily driving.
Or, find a way to lighten the load of the EGR , DPF, and other things that a bad for modern diesel engines.

Dilemma, keep the 2006 and fix it up? Buy a 2500 with a Hemi, and not worry about short daily driving? . Or, buy the 2025+ 2500 Cummins and just use it for longer trips and towing?
 
Lamont, Wyoming one year ago heading south on Highway 789/287. Population was 3 way back in the year 2000. The Analope Cafe in view was still open for those that will never leave. Otherwise, it's no longer in business. Entirely flat high desert terrain at an elevation of around 6,600 feet which is lower than our average Colorado state altitude. Towing our ORV 20BD Backcountry trailer against a headwind doing 63 MPH in a 70 MPH speed zone. Our Ram 2500 6.4L is screaming floored with the 4.10-1 rear axle ratio not helping much. Gas mileage from Casper to Rawlins sucked. A Ram 3500 passes by us with a much longer toy hauler in tow. I noticed that it was a diesel. It soon was out of our view. I made my decision then to go with the HO Cummins.
 
Just got back from a 11 hour trip (1 way) with 1200lbs of cement block loaded in the bed along with all the other equipment I had to drag along. I averaged around 16mpg and that was through the mountains of New England. I chose the 6.4 over the Cummins just because it's simple and reliable....unfortunately thats something you can't say for modern diesels anymore. The new Cummins have as many lifter failures as the gassers and everything about them cost triple to fix....add fuel prices that are almost a dollar more and I had a hard time justifying a diesel for personal use. If I was towing heavy on a regular basis or drove commercially I would go diesel because you can write off most of your expenses. Just my .02

My 2024 2500 Crew cab with the 6.4L and 3.73 has over 3300Lb payload. Might be the difference in the new gen frame. I can't say for certain, but I believe the same truck with the 6.7l had a lower payload.

His 2016 has a low payload because it has the Power Wagon package.

I believe he lower payload on the 6.7 is the difference in engine weight.
 
It’s here. Pick it up today. They’re installing the leveling kit as we speak and it goes in tomorrow for some 35 x12.50” Cooper Strongholds tomorrow

Had a 3hr commute home from picking up the truck. I averaged 17.4MPG on the computer going 65mph home. Relatively impressed, I did notice anything more than 65 and my mpg did drop.
