Do you really believe a 1HZ is just as reliable as an old slow ass 3B?
cause honestly I kinda have my doubts...
Not that I know much about them or have ever driven one...
I believe they are for sure, I have talked to many mining ops/mechanics (and visited mines) and they love the 1HZ, but they still have a soft spot for the 3b - many kept the 3b's out of the trucks when the frames and bodies rusted away - just couldn't part with the 3b that was still a strong runner. Most 1HZ's do get regular maintenance like someone said, but it all depends on the mine and if the vehicles are lease or under contract. Some mines have only 1-2 HZJ7X's and just do the minimums.
One mine that I bought alot of stuff from closed, they flooded their one section with 4 serviceable 3's, 1 pz and acouple of 1hZ's, with a ton of parts as well - crates of stuff - new windshield frames, tranny's etc etc. Wish I got to them before that happened.
