Congrats on the new truck , glad the nightmare is over for you.

1 piece of advice on that 5.4 , assuming it has relatively low miles unscrew all the sparkplugs , add a dab of anti-seize to the threads of each and screw them back in. When the aftermarket makes a kit to repair stripped plug holes and calls it the "Ford 5.4l plug thread repair kit", that's a big hint that some PM is called for. A big part of the problem is the plugs actually last 100,000 miles these days , so by the time you get to them they are really seized.
