Anyone skeptical of the OPs claim should really take just a few minutes to do some outside reading. Major problems with the 6.4L are not uncommon, and is probably the sole reason for the lower residual values for trucks with that motor.
Here is a good rundown of common problems:
http://www.fleetservicenorthwest.com/Pages/64powerstroke.aspxWhen you factor in the reliability, the poor fuel economy, and performance of the 6.4L to the V10 (pickuptrucks.com found the V10 could outpull the 6.4L on both 7% and 15% grades), its amazing people buy them still. I guess it must be the "Its a diesel so its better" mentality.
Not to mention... $17k would more than pay for a Cummins conversion.
