What diesel pickup to get

[jackelope]

I'm just about to the 1/2 million mile mark with my Excursion (7.3)

Quarter of a million on the f-350. Just maintaince stuff.

Quarter mil here on 6.4 as well.
350,000 on 7.3 before that.
A Chevy boy would have bought 4 trucks in that time frame.

Your 6.4 experience is the exception, not the norm. Hopefully you knocked on wood after you posted that.
Just checked this guy in. I'll update tomorrow.
