Without a doubt.I've had my '06 for 10 months and put 25k miles on it.Installed the lift,tires,bullydog,exhaust,and CAI all around 10K miles. Run her hard, but take great care of her. Change oil every 3K, fuel filter every 2 or 3K. No probs. Sure the changes are a little expensive to do so often, but there is no machine that can tollerate the use/abuse that these beasts eat and politely ask for more of. This is my second Cummins and I have come to the conclusion that one of themainreasonsa personwould ever get a new one is to have a new interior and a dent free, shiney new paint job
Ok, I also didn't raise my old one so I didn't know some of the abuse and neglect that it recieved from the previous owner and that really bugged me, so that was like 95% of why I sold it.
