In addition to the excellent comments above, things I always try to look at:

1) Passenger inner/outer fender for any sign of battery acid corrosion/rust.

2) Valve covers for leaks, feel behind intake manifold (behind distributor) for leaks.

3) Leak at transmission seal, pan or shifter lever seal.

4) Feel along the rockers and cab corners for bumps (rust).

5) Windshield seal good? Many leak in the upper corners.

6) Differential seal leaking?

7) Any water drips under radiator?

8) Power steering box leaking?

9) Test drive on highway at 60 MPH or so. Smooth? Gauges read ok, not overheating? What's the RPM (will determine how fast you can cruise on the HWY)?

10) With motor running and hood open, does it seem solid? (no excessive play indicating weak motor mounts?) Any smoke from exhaust?

Things to ask about:

1) Last time brake pads were changed and rotors turned?

2) Type of oil and filter used?

3) Has differential oil been changed since he owned? If so, when?

4) Last time transmission fluid was changed?

5) Any water leaks in cabin?

6) When was battery replaced last?

Looks like a great truck that someone has put a lot of time and money into. Hope it works out well for you.
