Most mileage on 6.0 trucks
 

Idk if this is common but my company truck has 412,xxx mile on it all original cept alternator, starter and waterpump. 2002 gmc 2500hd gas motor

can't believe the fuel pump went that far...other than that i dont see why not as long as maintenance is good. sounds like a highway cruiser.

I know it's a different engine and platform, but I was moving some trucks from a lot to another place to have plows removed and added, and drove a 2000 K2500 GMC with 494,000 on it, ran and drove better than an 04 F250 with 97,000 on it.

These trucks can be absolute tanks with proper maintenance. 200,000+ with ease, and as you can see possibly even much more.

My dads is a 99 2500 its got 355k miles and still driving every day. Only replaced radiator water pump started and fuel pump . These trucks are rock solid!
