Agreed, have both the 7.3 and 6.0.
In three of our 6.0's they had 170k miles bone stock with no major failures when purchased before we tore down to "bulletproof" only as preventative measures. Love the 6.0 and great motor after the work is done.
But still wouldn't choose to own one that hasn't had the preventative stuff done.
