I had a 50 cal can that I used for numerous VW's and then a couple Unimogs. They're heavy, but they work. THe one mod I made was replacing the handle on a 3# sledge with a short (as in hand sized) hunk of steel pipe with a nut welded to the end so it would fit...
THink what you REALLY need, what you can make do other things do, and what your capabilities are. But sure it's do-able for an emergency breakdown kit...
I found using these organizing trays from MTM Case Guard help with organizing.I used to use a 50 cal ammo box, but found it hard to extract tools out of if you filled it over half full. You either poked your hand trying to shuffle tools around to see the one you want. Or you dumped all the tools out and that was a mess. I found a small metal tool box that was wider/deeper but not as tall.worked much better.
Regardless, gluing a piece of **** carpet to the bottom of the tool box to keep it from sliding around in the trunk works wonders.
I found those 16" tool bags are much better fitted for the purpose...

The only annoying thing is cutting out all the dividers so it can hold tools. I really wish they just made some open trays. It also makes me wish I knew how to work with sheet metal and had a small break, then I'd start making my own metal ammo can trays.
If you aren't worried about keeping the elements out a tool bag would be better and a LOT quieter. If I had an SUV all of that rattling around would annoy the hell out of me. Would definitely have to wrap tools in rags or something.
Its pretty tight so it doesnt rattle. But now you guys got me thinnking about it moving. Hadnt had an issue with that in the couple months its been back there, but she hasnt had a wreck either. In a crash the last thing you want is a 25 lb metal box flying around and possibly injuring a kid

20170525_153831My Chevy 2500 has a nice spot under the hood to hold the double-wide ammo can. Made a custom bracket to hold it down. Out of the way, yet always there if needed. It has come in handy on a few occasions. Wasn't very careful on space management and could certainly fit more in there if desired, but this should cover most things. Looks pretty close to what you have, tool-wise.

If it's up against the seat backs it's unlikely it would become a projectile but Murphy never sleeps. Not that a bag full of wrenches wouldn't kill you but it's lighter overall. I have a rigid bin in the bed of my truck under a tonneau cover for all of my tools but that thing is super heavy. Held down with ratchet straps and a 2x6 in front to keep it from sliding forward.
