    Overheating can be caused by a wide variety of issues and sometimes isn't easy to solve. Since you seem to have a "slow overheat" rather than a rapid one, this sounds like a coolant circulation problem and not an air circulation problem.

    So you might check for a stuck or partially stuck thermostat, or a clogged radiator (especially on a 20 year old truck!). You can also buy a little kit to test for combustion gases in the coolant, which would indicate a head gasket leak. Most head gasket issues are rapid overheats, but as I said, overheating can be a complex issue and there are cases of a slow-overheat with a bad head gasket, and not all blown head gaskets will allow water into the oil--so just checking the dipstick for a milky substance (do this anyway) doesn't mean you don't have a bad head gasket.

    Aside from the dipstick check and combustion gas test in the coolant, you can pressurize the cooling system with a pump and then pull out the spark plugs, with the system still under pressure. If you see coolant on the tips of any of the plugs, then that's a sign of a bad gasket as well.

    You can also have soft radiator hoses that collapse at higher speeds, cutting off coolant circulation. That's another thing to check.

    Possibly an air block in the cooling system. Did you refill it carefully to eliminate any air, or "burp" the system?

    Is the radiator new as well?
