Is 300k miles alot for a Duramax diesel?
long-time-dmax A well cared for duramax that hasn’t been hot-rodded and such is just broke in at 300k LOL. Got 412k on mine and after driving this thing for 18 years, I see no reason at all that it wouldn’t hit 1 million miles pretty easily. And ditto on towing thru mountains with the diesel.

A well maintained rust free non-lifted LLY is still worth $15K-$20K, but if it’s been abused and lived in the rust belt, probably not worth much, even for parts. Mine has performed flawlessly for 10 years now pulling a 5th wheel for over 40K miles and I do all my own maintenance and minor repairs/upgrades.
