* Year: Fuel economy ratings have improved over the years.
* Engine: Different engine options (e.g., 6.7L Cummins) will have different fuel economy figures.
* Configuration: A heavy-duty truck with many options and a heavier payload will get worse fuel economy than a lightly equipped truck.
* Driving style: Aggressive driving significantly reduces fuel economy.
* Terrain: Driving in mountainous areas will reduce fuel economy compared to flat terrain.
Therefore, I cannot give you a single MPG number. To find the MPG for a *specific* Dodge Ram 2500 diesel, I recommend:
* Checking the EPA Fuel Economy website: This website (fueleconomy.gov) provides official EPA estimates for various vehicles, including different years and configurations of the Ram 2500. You'll need to select the specific year and engine of the truck.
* Looking at owner reviews: Websites like Edmunds, Kelley Blue Book, and others often have user reviews that include reported fuel economy. Keep in mind that these are subjective and may not reflect average performance.
* Checking the owner's manual: Your owner's manual should provide fuel economy estimates for your specific truck.
Expect the MPG to generally fall somewhere in the range of 15-25 mpg, but this is a very broad estimate. The actual number will be lower than this range in many real-world scenarios.
