Stop in for a cup of coffee

I wonder if there would be a market for a new diesel in a pickup that only had 300 Hp and 500 torque that got 25 MPG? You know those numbers were huge just a few years ago.... I mean if they focused on mileage like they have trying to one up the other brands. How much power do you really need???
Dodge did that with their V6 diesel. I think they had some engine issues though.
