Lately I've noticed that my dipstick has looked "milky" instead of normal. So I decided to drive around and get the oil circulated and then go underneath after the truck was off for a few minutes and drain a few ounces. Nothing but oil came out. Just wondering if waiting a few minutes was long enough for coolant (if there is any) to drain to the bottom of the pan?

 

Has the truck been getting warmed up when you've been driving it?

If not it could just be condensation in the oil that's not getting cooked off like normal.

 

because of my job I only drive a quarter mile usually, but once a week I try to drive over 10 miles so the battery charges. after letting the truck sit for a few hours, I went outside and drained a few more ounces and looks like reddish-black, not too milky.

 

I'd say it's condensation.

 

Will that damage my engine

 

Eventually. Need to drive it so that the engine gets up to operating temp, and then about another 15 minutes are so to boil off the excess moisture in the oil.
