However, due to differences in design features and technology enhancements, not all years provide the same level of performance or longevity as others do.

In general, it is best to avoid models from 2000-2002 as these were still equipped with mechanical fuel injection systems that often resulted in poor drivability issues such as rough idle or hesitation when accelerating due to air/fuel delivery miscalibration which could lead to more serious problems down the road if left unresolved for too long. Additionally, 2003 model year trucks also suffer from some injector related issues so they should be avoided unless you can confirm that repairs have already been made prior to purchase.
