I have replaced it with a 2002 F250 I purchased from a different dealership because, well, they had it and at a price I was willing to pay.
I would have been more than willing to buy from the previous dealership again. They specialize in trucks, and 4x4 diesels in particular, but they run across some interesting stuff. They buy primarily vehicles that were stolen and recovered, then auctioned by the insurance company that paid off on the theft. Interesting business model. I have no qualms about recommending them: Wheel Kinetics.
If you're interested in the now-repaired Nuclear Banana, here it is. Watch the video:
Good guys. It was a nice truck, but I don't think they'll sell it this time for what I paid for it. New EGR, new water pump, two more new injectors and a reprogrammed fuel injection control module. That could not have been cheap, and I wasn't going to put the $$ into it. They have.
