What could cause oil to be in the radiator water of my truck?

Head gasket.

Head could be racked or timing cover gaskets could be bad. I would start there cause they are like 20 bucks and only take about 1 1/2 hrs to change

Right. You have coolant and oil passages behind the timing cover, in which o-ring gaskets and a paper gasket may be the only thing seperating the two. Therefore becomes easily degradated
