My '95 has 232K. I was racking up about 20K/year over the past 4 years as the primary family ski rig, but have an '04 Sequoia Limited now for those duties that I just put 34's on that has 261K and is on its way to 500K if all goes well. Will probably take me 10 more years to get to 300K now on the 80.
HG was done as PM at 90K by the PO @ Slee (nobody should really understand what I just wrote there). I have done just about squat that wasn't an offroad or performance related mod or modernizing the interior since buying it in '05, outside of the water pump/fan clutch and a new custom exhaust (both this summer). It was running like crap with the fan clutch rotating in a fairly big ellipse and a y-pipe junction leak and disconnected muffler to intake pipe. Thing is running so smooth now that I need to address the little bit of vibe from the rear driveshaft.
Oh, and front axle rebuilds, definitely those. Have the PS to do in the next month. Probably ought do plugs, etc.
Now that she can afford some bench time, I'm working through these things hoping she has at least another decade in the stable until the kids are grown. Then I'll see if I'm really using a beast on 37's in an empty nest. Probably depends if the kids get into modding 4x4s and wheeling - they want to, but we'll see about priorities...
I can't see selling it because I'll want it the second it's gone, but I'd be lying if I said the Big Tree on a 2.5" lift running a set of 34's isn't a damn near perfect family rig. I'm gettin' old...
