123,000 on ours; it's in a Durango. I like it a lot. The thing has great low end and does very well towing a car trailer for what it is. The gas mileage sucks but we don't drive it that much. I was speaking with one of my mechanic friends last year and he said that he sees failure with the 4.7 when people do not keep the oil changed on a frequent basis. He said that the oil pick up is very close to the bottom of the oil pan and the ones he sees that have issues are gunked up at the pick up due to people not changing the oil when they should.
