I didn't read the whole thread yet but they run forever with the limiting factor being the body, if you're driving up salted mountain roads all winter it would be a good idea to get under there every summer with a wire brush and can of frame paint to keep it from disintegrating on you.
Also while you're test driving see if you like the way you're sitting, it's not as high up as a normal truck, the seats are a little lower so your legs stick out farther like in a car, it took a little getting used to.
Mine has a blue cloth interior which to me looks ugly as hell and is a definite reminder that its a 20 year old truck without any bells or whistles. So make sure your cool with that, after getting it I've always wondered what a girls perspective of it would be, definitely not oozing class nor very inviting, it sort of reminds me of my dads friends work and hunting trucks.
I don't know if my shocks are shot or if this is just part of the "truck like ride" but I feel like I feel every bump in the road.
I have a deck plate in my air filter so that could be it but getting much above 65-70 it makes a ton of noise and the RPS are pretty high, a reminder that this thing is more at home on shitty back roads then the freeway. Super charge is always an option if the speed bugs you that much.
Other then that, I love the thing. Has taken me to so many cool spots and trail, road trips, and it's cool knowing it will probably still be running with 200,000 miles if I take good care of it and could probably pass it on to one of my kids if I don't ever sell it. And it climbs like none other. Mines completly stock and sometimes I'll see "wheelin" trails on my way to a trailhead and just be like "huh I wonder if I can make it up that" and usually do.
