Picky? How drunk were you when you bought the last project
Check trans fluid. Check rear end for leaks. They are easy to fix, but chances are if it's leaking, it was driven with low fluid.
Cab corners for rust. Check oil level. If it's low, then it prolly burns a little. Can check tip of exhaust for same problem. All maintenance stuff on these things is pretty easy, so I wouldn't be OVERLY worried about it, but trans/rear end repairs get expensive fast.
