Never hurts to add a set of fuel filters and perhaps fan belt as well to any tool set in the trunk. Some specific tools let the kids share as one valve adjusting set for example should be enough unless the kids live far apart. Spare glow plug strip fuse and an assortment of normal fuses as well I guess do not hurt either. Plus at least enough tools in trunk to change the above.

Jesus! "Cut me Mick..."

I would recommend all the metric tools mentioned before, a ratcheting box end set of wrenches, a glow plug reamer, the valve adjust wrenches, and a 27mm socket.

A good set of screwdrivers: 4" common and phillips, stubby combination driver
Hemostats
Mechanical fingers or even better, an LED lighted-flex magnet.
Nitrile Gloves, safety glasses (inside of an old sock), painters coveralls, and fender cover that will double as a ground mat.
Flashlight (One with Super-Bright LED's)
Multi-purpose electrical tool with stripper blade and crimper. (handfull of red and blue splices)
Small tube of silicone grease. (Great stuff! waterproofs elec. connections, gasket re-vitalizer and overall emergency lube.)
Bundle of red rags or roll of paper towels
Hand Cleaner (small tube)

Wrenches
 

I like the stubby 22mm and 17 mm combination wrenches for the lines at the fuel pump. Hard to reach with conventional length wrenches.

A well stocked fridge

lots of rags
several cans of non chlorinated brake cleaner
more rags

.... I like this thread.. I'm about to go on a long trip, and am going to use this thread to pack my tools... This is going to beat bringing too much and having to dig through it all..:D

,..Peanut oil
Golf tees
spare fuel filters.....

what tool and size of tool do you use to remove the fuel sending unit???

Since I have stripped a few of these 123's I kept one of every heater hose + a 4 foot roll of new fuel line hose & I pack this all underneath the spare tire in that empty space. Real Simple you put the big hoses underneath then fasten the spare in & you can stuff all the small hoses & other stuff thru the gaps in the rim. It is nice piece of mind for a car you take on a long trip , it weighs nothing & its free if you have a parts car. Of course I stuff a set of good used belts under there too. Only put stuff like this under there because metal tools will make noise rattleing around unless you wrap them up good in cloth.

Other items I carry on a long trip:

* Fuel filter & pre filter
* 2 Wrenchs of each 8,10,13,14,17,19,22,24 mm
* Vice Grips , Cresent wrench, other small tools etc
* plastic cable ties (underneath spare)
* a quart of every fluid (except diff)
& a couple other things I cant remember right now.

When did this turn into a "What do you carry in your trunk?" thread?

It's all good advice! I carry spare belts in the trunk, with a small tool kit.
Got to demonstrate to my oldest son last year when he was 15.

We were driving back from Oakland, CA at night when the power steering belt
broke suddenly. I explained what happened, and showed him what the steering felt like without power assist. Got home and pulled the spare out
of the trunk and put it on. Thought dad was a genius...

Steel tipped shoes. You are gona need to kick something REAL HARD every once in a while, may as well not hurt yourself :-)

A small (one ton rated) hyraulic floor jack and blocking along with a half-inch breaker bar and short extension and hex socket for wheel lugs. There can always arise a time when you only have soft shoulder to change a tire & the MB-supplied jack may not have the necessary stability. Battery-powered fluorescent trouble lite. Hosing of various types. Obviously I've focused here on on-the-road tools.

I got some really handy Craftsman wrenches ("Flex Gear Wrench") that made certain jobs really easy. You can work in really tight spaces w/these wrenches--they ran about 70 bucks for a set of 5 or 6, well worth it.

What tools are essential to maintain a diesel?
