Go for the Dodge . We have a brand new Chevy 6500 flatbed wrecker with the Duramax / Allison combo . That truck IS the biggest piece of shit on the road and pricing in at almost $70,000.00 you would think it would be a gem . We also have a 05 F550 wrecker with the 6.0 again another pile of garbage . This truck has wiring gremlins , trans problems , coolant leaks , boost leaks , and every bushing up front needs replaced and it only has 45,000 on it . Yeah that is alot of miles but it is a tow truck and is used 24/7 and the Fords pricetag was higher than the Chevys . Moral of the story if International still made the 97 D444E 4700 and it was in pickup truck form Id buy one yesterday . My daily driver is a 94 Ram 2500 with the 360 and it still pulls like a freight train . Stay away from the duramax. - Joe
