According to the title and the title history (from carfax.com), this is the actual mileage.

The oil pressure problem has been present for as long as I have owned the truck (6+ months). But the engine doesn't have any bad knocks, except for some valve or lifter noise on heavy accelerations.
I'm inclined to try the oil pump replacement, see if there's any metal in the oil pan. If that doesn't work, then I suppose the engine will need a rebuild. I'll probably put that off for as long as I can since I can't afford to put that much dough into the truck right now.
The engine seems to have decent power, I was able to tow a bobcat with the front-end loader and backhoe attachment from Santa Fe to Pojoaque (uphill both ways
) without too much trouble.
