if ur lookin for pulling pwr, go with the dodge. i got 100k on my 06 and (knock on wood) no issues with the engine area yet. dont look for good milage though. i had bout 12k, trailer and load and my milage was down to bout 8-10mpg. the milage will vary with every driver but when i was in iraq my last tour a friend of mine and his dad had a pullin contest with the tcks. my friend had my tck, 06 5.9 cummins w/ 6spd 4x4 and it was stock at that time and his dad has an 04-06 duramax. they both loaded with 20 round bails each and the the cummins left the duramax behind. that is just my history with the both tcks. every tck is different as is every driver, with a diesel, the engin aint fully broke in till bout 60-80k miles but i would buy anything over 150kmls w/o known the maint history. best of luck on ur shopping
I agree, we have an 06 dodge 1 ton with over 100k on it and it runs and pulls good. Never been in the shop for anything mechanical (knock on wood). A good friend of ours had the same identical truck and traded it in for the 09 duramax and he regrets it every day. Says that he wishes he had his 06 dodge back.
