I have owned this truck since it was new in 1994. It currently has 210K on it and still runs like new. I have replace consumables; i.e., water pump, battery, alternator. Nothing major until I replaced the suspension last year. This two wheel drive outperformed many on the trail, in snow storms and through rivers and stream beds. No complaints, I'd do it again.
This truck has never let me down. It has not necessarily been given the best of care and still has been the most reliable vehicle I have ever owned. Even with the 4.9L I-6 this truck tows incredibly well; boats, horses and up mountain roads.
The changes I would have made to this model since 1994 were to the interior only and have since been incorporated into the newer models.
