Yeah, the Cummins were great motors, the rest, not so much, at least early on. Dodge maybe had the rest up to snuff by 03. I have seen a sheared off transfer case on an older model. Also heard the trans and rears blew up as well, again the older models. Not sure why the RE series trans were so flakey, old Torque Flights were bullet proof. Those 7.3 Superduty were great trucks all around.
