That is SO much better than what I have going for the actual hand-tool organization. I also have a RZR so I have an Action Packer that fits into a rack on the back of the RZR:

Mine is actually configured the other way, cooler more re-ward you can just see it here:

Thus far for Overlanding I've just been taking it out of the RZR and throwing it in the WJ (I take out the RZR-specific stuff like the spare drive belts). I also throw a bunch of my Dewalt tools, a 12 ton bottle jack, etc. into the WJ in either another bin, or down in the the footwell of one of the back seats.
As for what's actually in the Action Packer, I have a "Dirt Bagz" in it for the handtools:

It's a nice bag, but everything is just tossed in. There's no organization and the tools get beat up pretty badly. I have a similar assortment of tools as you (though no torque wrench) but I also carry small spools of black and red wire and lots of butt-connectors, terminal ends, etc. and wire crimpers. I'm actually a big fan of having these:
in the tool kit. I'd say it's been the case that we need to repair wiring or hot-wire something just as often as we need to do a mechanical repair. So all of that goes in the Dirt Bagz, and the bag goes inside the Action Packer.
Then I also throw in my little lithium jump pack, some real jumper cables, a check-ball siphon hose
(so you don't have to such fuel... which is no bueno and never seems to work without somebody getting a mouth full), a good assortment of zip-ties (including some really long/heavy-duty ones), Colby valve stem, tire plug kit, some ratchet straps and probably some other junk I'm forgetting.
I'm about due for a re-inventory and re-organize session on the tool kit. Oh, and I also throw in one of these:

I scored it during a 50% off sale so I actually grabbed a couple. One to keep in the WJ and one for the 5th Wheel. Between what's in that kit and what's in the kit from the RZR I have a fighting chance at fixing most anything. The biggest difference with the WJ is I need more, bigger tools. So I added more large combo wrenches (making sure I have 2 of the sizes that fit the jam-nuts and such on my suspension and steering components) as well larger crescent wrenches, and one of my favorites: the crescent vice-grip:
