93 Chevy 2500 flatbed with 3116 Cat Diesel. Issues?

[Lynn]

May have a chance to buy a 93 2500 with the Cat 6.6 engine.

EDIT: UPON FURTHER REVIEW, IT MAY BE A 6.2 DURAMAX V8 DIESEL, NATURALLY ASPRIATED AND A BIT UNDERPOWERED. IF SO, I AM NOT INTERESTED.

Body is pristine, but paint is faded.

Not a dually.

Flat bed (was sold as an "incomplete" truck).

Auto trans (would rather it had a 5 speed).

67k miles, but been sitting for a while.

A buddy of mine let his old Dodge truck sit for 6 years (Cummins Diesel). All he did was change the oil, put in fresh fuel and start it up. Apparently diesel fuel doesn't turn to varnish like regular fuel.

I may take a HD battery with me to go look at it, to make sure it cranks.

Any reason to shy away from this engine? Seems most diesels are good for at least 200k miles.

I have never owned a diesel.

Any advice?
