I'm suddenly amused by the idea that you could tell him fine that you will take back the truck and then he would fly the plane in again and have to drive the truck in as well. Then when he gets there just say "Oh I changed my mind" (Like he did), and then he would have to drive back another two hours plus wasted plane trip and gas. Mean but that dude is crazy. Who knows what he's done to that truck in the mean time.
