Sorry to xpost but need all the quick help I can get

Went to look at an F350 for sale here locally. Thing has been sitting for at least 6 mos. and I've been glancing at it as I drive by for quite some time. Was a voluntary repossession, 220xxx on the clock. It's 2wd, 5spd, and PSD. The thing has an incredibly flat pass front tire so it's not drivable atm so no idea on clutch feel or how it actually drives yet.

They're asking $2,500. It DEFINITELY needs some work, will pretty much need 6 new tires, a new tailgate, front bumper is falling off, a few minor rust spots, driver's seat looks like a bobcat's been living in it. Once I powered it up with some jumper cables it fired right up. idled nice and smooth, not a single bit of smoke. Let it charge, turned off, and fired right up again. All lights were working, couldn't tell about gauge lights, too bright outside. I turned the AC on full blast and in the 2-3 minutes I had it idling it never got cold. Diesels are so loud couldn't tell if the compressor was kicking on or not, do you think it might just be the fact that it wasn't moving at all just trying to get cold on idle? Only other thing I noticed is when I shut it off it shuddered noticeably. I'm 100% new to diesels so would like some help here.

Took lots o pics for your eye pleasure.

Interior:
No radio, but what's missing in the hole on the bottom?








Nice bud light bottle cap shift pattern. That adds at least $25 to it, right?


Exterior







This tire has become a rubber puddle.




Tailgate's destroyed and won't open ALSO in this picture does it look like frame damage? Or is it just how flat the front tire is making it flex so bad? I've seen that these OBS Fords have some crazy flex between cabin and bed but not sure if that's what I'm lookin at here.
