Hmmmmm thats a really good question and all I got to say is ive owned two power strokes one cummins and three DMAXs and really pound for pound the cummins are better trucks in my opinion mine was an 05' and I drove the piss out of it put 300,000 miles on it and it still ran great pulled stock and race trailers with it and it did just fine plus they sound great if you put a 6in. open pipe on it and let r eat!!!!! :wink: :wink: :wink:
