My 4.7L Durango SLT Plus AWD has 176K on it. I bought it used with 12K on it. Replaced water pump, replaced radiator, three batteries, two sets of tires, one set of plugs. Nothing else has been touched. 15.5MPG mostly city. Passes the second most strict emissions in the country. Towed with it 5 times a year in the Rockies, once over Trail Ridge road, the highest continuous road in the nation. Oil changed seasonally (four times a year), about 5500 miles between changes.
All in all, the best vehicle I have ever owned.
