Project find -- Thoughts before I pull the trigger? Chevy 3600

[gigamanx]

Hey all,
Found an old farm truck that I'd like to take a look at. Originally looking for a 3100 but my research tells me a 3600 is the same thing with beefier undercarriage. Clean title and seems to be in running condition. From the CL pictures, looks like I'd need a new bed and running boards from LMC so ad maybe $1500 and I've got myself a good starter for a future rod? I'm new to this so hoping the forum can pick up on any major issues up front

$2500 seems pretty decent compared to other prices I've seen for crappier trucks.

TIA
