What swayed me away from moving up to the Cummins?
1. Prices are insane. 4 year old trucks with 100k on the clock are $45,000. New ones lease like s*** compared to a half ton, with monthly payments that are literally double.
2. 5'7" box not available, which means I'd never be able to use my residential garage ever again.
3. Fuel mileage is identical to a 6.4L Hemi while towing, and is only 3 MPG higher when unloaded. And compared to EcoDiesel I'd lose a solid 5-6 MPG in typical daily driving.
4. Washboard ride quality.
5. Payload is only 400 lbs. greater than a Gladiator/Ram 1500, unless you go Ram 3500 and then every one in stock is a dually.
6. Maintenance intervals are even more expensive than the EcoD, if that were possible. More oil, double the fuel filters, etc.
So I think I'll stick with the EcoD trucks. Tunes are coming out this year. IF we can get close to 600 lb/ft of torque at the crank, which is certainly within the realm of possibility, then we'll have the same power to weight ratio as a stock Cummins truck, but in a package that's garagable, parkable, and a lot more fun to daily drive.
There is no way a hemi gets same MPG as cummins, either unloaded or not. People tend to gloss over the differences to suit their narrative, because what's 1 or 2 mpg difference; but every MPG difference is extremely significant. If you tow with a hemi and get 9 MPG, and tow with a cummins and get 12 MPG, that looks tiny until you turn that into a percent and realize the difference is 20% to 25%.
For payload, it is quite low on a 2500/cummins vs a 2500/hemi, but you can find many cummins north of 2000 (especially in tradesman/bighorn trims) and also keep in mind that 100 pounds overloaded on a gladiator is a far bigger problem than overloading a 2500 by 100 pounds.
Gladiator cannot pull 17000 pounds (what the 2500/cummins can pull) no matter how much you tune that ED.
