Class C Diesel MPG Question

I agree with all of the above about "Ford" diesel engines. IIRC, if you check specs, you'll find he Van/Class C iteration of the Diesel does NOT produce the HP and Torque everybody brags about in pickups. There are space and cooling issues in the E-Series so the diesel is de-tuned. The V10 performs about like the PSD in a pickup. The V10 will outperform the PSD in a Class C.

I want a Ford Chassis, Cummins Engine, Allison Transmission...
