It is water in the oil. My truck does the same thing, it is condensation that builds up inside the motor, and it goes to the highest point in the motor which is the cap. It shouldn't hurt anything, because from what I know all these trucks do it under the right conditions.
and if you were thinking you had a blown head gasket don't worry, I thought the same thing when I saw it...

I have seen this quite a bit when I worked as a mechanic. It usually is from just minor moisture and no big deal. If your oil looks normal then just clean the cap off with brake cleaner or such and you should be ok. But keep an eye on it just in case. If your oil is milky. you have a bad head gasket.

normal during cooler ambiant temps. if the oil on the dipstick is good dont worry. every vehicle i pull into the shop during the winter is like this. the oil cap is tucked up in that tube so hot oil does not hit it to wash it off, infact before starting your vehicle both valve covers would look like that as well.
