More coolant, and a spare electric fuel pump for the truck. From what I can tell, I need to purchase a new 4x4 actuator for the truck. The damn thing kicked into 4x on my way home from the boss's house. Then it wouldn't kick out of 4 low. After futzing with it for way too long I finally got it back to 2x and crawled under the truck to pull the electrical connector, and drove home...
