Took delivery one year ago today- 29,500 miles later truck has given no problems except a death wobble which I cured with a different front shock set-up. The BHAF had to go courtesy of Cummins techs who shook their fingers at me but that is all. The engine showed no abnormal wear in an oil analysis done after they discovered that a lot of dirt and sand had gotten into the turbo. Normal ( virtually no) oil consumption between changes. I now have Premium Blue Extreme Synthetic in and will extend the intervals out to 7500- I had been dumping it out at 3000-4500 miles with dino. No steering problems or other concerns and as far as I know the lift pump is fine. I like this truck and look forward to some gauges and a better stereo but that is all as I like the reliability of stock for now. I just wish the 03 wasn't so improved I get tempted.
