looking into 72, advice wanted

[Peregrine]

I dropped the idea of restoring my dads 82 because the body is too far gone and I could do it, but it'd take forever and I'd need resources I don't have. SO I was looking for older cars and I found a nice 72 c10 for 6 grand. The guy who has it now uses it as a daily driver but wants to get rid of it cause he's gettin tired of sitting in rush hour traffic without A/C. He got it 3 years ago at an estate auction because the guy who restored it died. THe previous owner did a off-frame resto in 1995 and it won two car shows. It's cherry red, no rust, lowered, 6 year old 350/turbo400. Also has a 14 galon fuel cell. Anything special to look for? I kinda know my way around these trucks because of my dads 82 but it seems every model has a certain weakness that I don't know about (like Chevelles rusting by the rear window) if you wanna look at it
here it is
