I'd vote 7.3. Having owned 2 OBS trucks well over 200K, one had 290 when I sold it, they were both solid as far as reliability. I spent some cash fixing seals and wear items but certainly not 60k worth. Find a rust free one and enjoy for years to come. I have a friend with a new 6.7 that's been in the dealer 3 times already for sensor failures and such. Only put it in limp mode once but still, what a PIA. I think the new diesels are much better since their introduction in 2008 but I still think there is some room for improvement and reliability to trust it in the backcountry, no where near a dealership. There are few places in North America that haven't seen and worked on 7.3 motors. The modern Diesels need either a dealer or a diesel specialists that has invested in all the tools to diagnose these rigs.
Either way, you'll have a fun truck to play with when you get it.
