Mine had like 100 miles on the odo and a little sticker on the driver's side window that said "This vehicle has been subjected to a random DC quality audit. The miles shown on the odometer will not be deducted from your warranty" or something like that. Anybody else have one of those? It's been a great truck so far, so whatever they did was fine by me.

 

I think ya'll are a little paranoid about the engine, although can't say as I blame you considering what these trucks cost.
The engine doesn't require a break-in, get it to temp and go. The break-in is for the rear-end.
I wouldn't recommend red lining it, but I try not to do that anytime unless I'm running from the law!

PS: I'm sure someone will disagree, but they aren't paying for my truck.
