Did not I read somewhere on this forum that a software update (TSB) to the BCM for something had CHANGED the DRL lights. The OP states in post #10 "Took my truck in for an oil change a few days later and a once over ". MAYBE he got a software update during the "once over". OP, does your Service Receipt say anything about a software update?

The park lights are on during day when the truck is placed into gear.
