I did build a piece of gear for the LJ Safari today...
Back when I was designing the Exogate large spare carrier/tailgate reinforcement/heavy-duty hinges, I did a number of designs for things that could be used along with it, given the fact that once the Exogate is installed, the tailgate has a lot more weight capacity.
One of the things I designed, but never built (until now) is a jerry can rack that sits between the factory spare carrier and the tailgate. I've got a very long cross-country trip coming up in January, and I'll be crossing long stretches of fairly desolate terrain, so I'd feel more comfortable if I had some spare fuel on board. Also, all those miles will be a good chance to give the design a thorough test.
Here is it, just tack-welded together so far, but complete except for a locking strap that will secure both the can to the rack and the cap to the can. Don't mind the dust and dirt, the tailgate and carrier I'm mocking this up with are spares from my dusty garage.
Disclaimer 1: I'm mocking this up on my workbench on a factory tailgate without an Exogate, but this doesn't mean this rack should be used without some form of tailgate reinforcement. I think if this were installed on an unreinforced factory tailgate, the life of the tailgate would be significantly shortened.
Disclaimer 2: I'm building this for my cross-country trip, just because I built it doesn't mean it will become a product. Just thought you might be interested in seeing it though.
Once I fabricate the locking strap, everything will get painted and then I'll install it on the LJ Safari.
