If you are picking up next week... Look around the forum for things that are easily missed on the PDI.
If I was buying again, I would make them do the alignment and adjust the Hellwig helper springs before I sign off on it. Also check to make sure the levellers are a minimum 7"-8" off the ground, per manufacturer specs. Many of us found them as little as 6 inches off the ground which makes them prone to damage on any significant grade. I could not get mine into the driveway at home without them bottoming out.
