How Does the New Ford F-150 Diesel Compare to the Nissan Titan XD Diesel?

The 3.0 Power Stroke is the first diesel engine in the long history of the F-150. The Cummins 5.0 is also the first diesel for the Nissan Titan. So how do they stack up?

To be fair, we compared a 1/2 ton truck to a heavy duty truck. The Titan diesel has more power, more torque, and a higher tow rating. But the new F-150 tows more than 11,000 lbs and offers better fuel economy. Got a trailer to tow? Which would you choose?
