What make, model, Year diesel has been known to have best mileage?
 

Without the usual brand bashing etc....with no regard to anything else but the best fuel mileage, what year, brand and model of diesel truck, in stock form, is known to have the best fuel mileage? For someone who is concerned primarily with getting the best mileage with a 3/4 ton or 1 ton truck.

I think Dodges do...

You could get high teens out of 7.3L Powerstrokes.

I don't know squat about DMaxs.
