* Model Year: Older models generally have lower fuel economy than newer ones. Improvements in engine technology have led to better MPG over time.
* Engine Size: A larger engine will generally consume more fuel than a smaller one. Dodge Rams have offered various diesel engine sizes over the years.
* Trim Level: Heavier trim levels with more features and options tend to have slightly lower fuel economy.
* Driving Conditions: City driving typically yields lower MPG than highway driving. Terrain, weather, and driving style all play a role.
* Payload and Towing: Hauling heavy loads or towing a trailer will dramatically reduce fuel economy.
Therefore, there's no single answer to your question. To get a more accurate estimate, you should specify the *exact* year, model, and engine size of the Dodge Ram you're interested in. Then, you can consult the EPA's fuel economy website (fueleconomy.gov) or the owner's manual for that specific vehicle. You'll find ranges given for city and highway driving. Keep in mind that real-world fuel economy might differ from the EPA estimates.
