Great link, interesting reading. I think in addition to loaded weight the maintenance, and driving style (ie towing?) have a large impact. I just bought a 2000 with 180 K km on a Dodge 5.7 (360 cu in). It was a rental for 2 years and 55k km, then owned by a sinlge older lady for 13 years and 135K km, but she did regular 5000 km oil changes and 3 trans flushes (she had all the receipts) and I doesnt' have a tow hitch at all. so I took the "chance". Purchase price was reflective of the high mileage, so that helped. The unit has literally been from the arctic in Alaska and NWT, to Florida, maritimes to San Diego, so criss crossed the continent. Hope it will serve us as well and I wont' be doing those kind of miles per year, at least yet.
