Don't know if this'll help you, but here's a list of what I travelled with in the trunk, when I travelled 1/4 of the U.S. in my '83 300SD with 305K miles on it:

* Set of tools
* Jackstand
* Floorjack
* (1) set fanbelts
* Oil filter
* (1) set of fuel filters
* DC air-pump to air-up a slow leak tire
* Assorted exterior vehicle light bulbs
* Work gloves and safety glasses
* Section of cardboard to lie on under car
* Rags/shop towels
* Fast Orange hand cleaner-degreaser
