Excellent find on the cover. That's a good price if it's in good condition.

Only take the air dam as far down as the lowest hanging pieces of your undercarriage, but as far out to the sides as possible to cover the tires. Lower than that and the improvement gets negated by the increased area.

Besides that I've read stories that described improvement all the way down to the ground, but every time the dam scraped the road the driver would grit his teeth. There's a point beyond which the improvement in performance isn't worth the added discomfort.

Looking forward to seeing how this goes. Start a garage page for your truck and we'll all be able to follow along.
