How many miles on your truck without engine issues?

Just wondering how many Duramax diesels are out there that have run thousands of miles without any engine issues such as water pump or head gaskets, etc.

If you've had no issues so far, post the miles on your odometer, please! Let's see how many trouble free trucks there are!

Mine: only 80,000 so far, but no issues.

240,000. Havent touched the engine, except the idler pullies, belt, and thermostats at 150,000, just cuz I thought I better. It needs 2 new injectors, but still gets 17 mpg with 33 in tires. The Duramax has been FLAWLESS, no complaints! The Allison on the other hand is a different story. Its about ready for its 2nd rebuild. P.S. It still has the original front suspension parts, minus 1 front wheel bearing.

75,000 miles and the only real problem has been the drivers side wheel bearing. Of course there's been a bunch of wearable items like the brakes, batteries, and shocks. My biggest complaint right now is my seat heaters stopped working
