Fuel tank size.
My fuel light came on in my new Ram 3500. I was near a diesel station so I filled it up - could only get 25 gallons in! It is a 31 gallon tank. Does this mean I have a 6 gallon reserve after the fuel ...

Changed my stock tank out for a 65 gallon under bed tank. My light comes on with 10 gallons in reserve. The stock tanks are just way too small... especially if you live in the country or when towing.
