I'm knocking on 250K, bought it with 163K on the dial. I drive the poo out of this truck. I've put THREE ZF6's in it, three clutches, waterpump, some seals, brakes, two sets of tires, and a few other items.
Anyone that's been here a while knows all my tranny issues, mostly mistakes while doing something else or going to a BAD repair shop. Clutches were either me getting the wrong part in the first place or a man. defect. Water pump just replaced for the first time a month or so ago. (Thanks Marty!) Turbo seals, rebuilt turbo etc.
Really and truly, I can't complain a bit!!! 90% of the money invested in repairing the truck is either performance enhancing or due to mine or someone else's mistake. With a 1/4 of a million miles, I'm gonna keep good 'ol Brisco for a while and see just how many miles I can get until he drops a rod or something catastrophic breaks.
