Quick update:
Took it to the dealer I bought it from after work today and took the service manager for a ride (granted this guy treated me well in the past, when I bought it he changed both cats and the plugs for me!) It made the noise clear as day and he heard it too. It was most clear around 50-55mph, and he thinks it's definitely something mechanical coming from the engine, but he has never heard anything like it. He also said since its not hurting the performance of the truck, and it would take hours to try to diagnose, he said not to worry about it until it gets worse then he'd "take care of it for me"
We'll see what happens

I'd get that in writing.Worse will probably equal more expensive.

Ha! I know..that's what I'm worried about..I'm just gonna drive it. If something does happen I'll raise hell with him. I think it is a pulley though. This morning it was about 35 and before the truck was warm (when I first started it) it heard a rattling, bearing kind of sound (like a pulley would make) coming from the grille area..I don't know what else it could be

I may call him back and say the noise is getting worse and make him fix it

Yeah, I suppose it could take hrs to find but you could quickly figure out if it's a pulley making the noise. How long is your warranty? Kinda sounds like the SM is trying to snub you.

Put the truck in a lower gear and get the rpm up into the range you are running on the highway. Drive it steady at that rpm and maybe you will be able to single out where that noise is coming from, or have a partner rev the engine to the right rpm and do the stethescope trick if you can duplicate the noise running in a lower gear. That does not take a rocket scientist to do, or a Ford trained mechanic!
