You'll be fine with a 7500 mile interval. There's really no need to choose the severe service schedule for your conditions unless your truck idles for hours at a time. Also, the Ford 5.4 has a 7 quart sump, so the oil is probably not going to be as stressed.
Motorcraft 5W20 is a good choice. Then again, as is any 5W20 engine oil.

That's what I was thinking as well. On the
Ford website, they always have a coupon for a $39.95 special for a minor service. For your truck, since the sump is seven quarts, the price is probably $6 more, but it's still a great deal.
