It should be very quick and easy to see where the oil came from when it's on a lift. The filter may be tight because it is cross threaded and certainly not sealed at the gasket.

I would not go directly to the service department and let them try to cover themselves before the manager is involved. Tow it to the shop, go in and ask for the service manager and owner. You are driving a top end vehicle, have them treat you like a top end customer. In other words, set the tone that you mean business (in a professional way) and play it from there. I would have all of you go into the shop together and stand under that truck and see the same thing at the same time. Take pictures, document and then turn to the owner and ask, "What now? How are you going to make me whole?" If he says he will simply redo the oil change, decline and say you will take it to a shop authorized by your insurer and double check the damages. He has a fund for these types of mistakes, without involving insurance companies and/or the Toyota Corp. Always keep that threat in your back pocket.

Hilton Head is certainly not the place to be this weekend, but good luck.
