Thank you 2freelife fro coming back and stopping the peeing match.
No reason to believe your truck won't have a lot more good miles in it if it's as good of shape as you describe and not rusted out (WI, dontcha know).
A few things to think about though. 05, 150k miles iirc, that is about the time that some of the components start wearing out. Of course every vehicle is different, but in the next 100k miles, the common issues are front unit bearings, u joints all around, power steering pump, injectors and steering components (ball joints, tie rods, etc) and the transmission.
Without overthinking it, it's reasonable to think that you will incur half? of these repairs.
Not trying to scare you off your truck. IMO it's a good platform for long life/high miles. Just a consideration.
