I thought about the cummins 12v but I would have to mod too much I wanted a Powerstroke also but me and the wife want mpg. I live an hr from town. People say the get 26 mpg with the 12v but find that hard to believe. What I want is a cumins 4bt with a p pump. They cost WAY TO MUCH. I found in 2500 not including shipping and needs a rebuild.
Mb have any larger diesel?
By the way the Isuzu and cummins is a 3.9l
