Through a series, of what looks like completely unbiased, tests it seems a winner between the eternal struggle has been found. I’ll post a link to the site after I give you a little bit of the testing information.The Contenders:

2005 Ford F350 6.0 Liter Power Stroke Diesel 325 hp @ 3500 rpm 570 ft. lbs @ 2000 rpm

2005 Dodge Ram 3500 5.9 Liter Cummins Diesel 325 hp @ 2900 rpm 610 ft. lbs @ 1600 rpm

2005 Chevy Silverado 3500 6.6 Liter Duramax Diesel 310 hp @ 3200 rpm 605 ft. lbs @ 1600 rpm

They go through a comprehensive series of tests from interior quality to offroading at Tellico ORV. You won’t believe the results. These vehicles were even subjected to a vicious animal attack, and you get to see how well they survive.
