I have been saving my spare change for some time now and sometimes this month intend to purchase a used Ford truck. I can't stretch my money to get a 6.7 and, from what I've read, I'm going to avoid the 6.4. I have zeroed in on a few 6.0l that the owners claimed are studded and deleted (all of them between 175k and 225k). I'm searching down south because I want a good looking, rust free truck (almost an impossibility here in Illinois). As I begin to look is there any advice? I'm always geeked when I see that a truck I like has been studded and deleted or bulletproofed, but I have a feeling there is more to buying a diesel than that. This truck will be a daily driver and I don't plan on towing or hauling anything with it.
