30 Mpg from a small diesel in a small truch is certainly possible, if the truck is designed small enough and slick enough, but whether it holds up as a rating for the EPA Combined test cycle remains to be seen. Trucks this smaller with even smaller diesels are used in Asia and get mileage in that range by local test standards. The great mpg is because the truck will require so little power to move it, just as a subcompact car does so much better than a full-size SUV.
30 mpg towing? Don't expect it. The power needed to move is determined by what you are towing, and how fast you are towing it, more than by what powerplant is in the tow vehicle. Turbo gas like your Ecoboost is almost efficient, HP-hour per pound of fuel, so gain from going diesel will be mostly from fuel density if you measure mpg rather than miles per pound. With today's motor fuel price structures being so even on pounds per dollar, miles per dollar might not be much of a gain.
