* Engine: The 1995 Ram 2500 diesel came with different engine options (likely a Cummins). The specific engine significantly impacts fuel economy.
* Transmission: Automatic or manual transmissions affect fuel efficiency.
* Weight of the tow: Heavier loads drastically reduce MPG.
* Terrain: Hills and mountains will significantly lower MPG compared to flat land.
* Driving style: Aggressive driving reduces fuel economy.
* Vehicle condition: Proper maintenance affects MPG.
While you won't find a precise number, expect significantly lower MPG while towing compared to city or highway driving without a trailer. A reasonable estimate for highway driving *without* towing might be in the 14-18 MPG range, but this is a broad guess and could be higher or lower depending on the factors above. Towing could easily drop that to 8-12 MPG or even lower, depending on the weight of the trailer and the conditions.
To get a better idea, you might try searching online forums dedicated to classic Dodge trucks or the Cummins engine. Owners there often share their real-world fuel economy experiences.
