Picked it up on Thursday and then left for the weekend on a hunting trip. Just got back this afternoon after being separated from the new truck and my son (9 years old) asked me if I'd tried out Sport mode. I told him I forgot all about and proceeded to put it in Sport mode. Let me just say that it is scary how much this truck changes from a gentle giant to an absolute beast just by changing the driving mode. I can't even imagine how much power this thing will put down when someone comes out with a tune for it. I've heard Ford Performance will be coming out with one soon that doesn't void the warranty. I better start saving my pennies.
By the way, this is the nicest, most beautiful truck I have ever driven/owned. Ford hit it out of the park with this truck!
