Who's in Atlanta? Look at a diesel 3500?

[PatDTN]

I found an ad for a 2005 3500 diesel pickup I'd love to get but it's a "mechanic's special." Carfax says the long block was replaced, seller says it isn't running right and won't go far. I'm East of Knoxville and had hopes of riding my bike down to bring the beast home. It would be nice to have someone with knowledge look to see how bad...

Thanks for reading.
