I modified the stock rear bumper to hold water for washing not consumption (I would drink in emergency). It is great. I did mine a bit different than in the link above. I put a 1/2" plastic elbow (threaded on one side and barbed on the other) on each end of the bumper so water would be picked up no matter the angle of the jeep. I then threaded it into a hole i created on the bumper and sealed around it using Plumbers Goop. I then attached 1/2" clear line to the barbed end with a pipe clamp and ran it down the bumper mounting it with superglued zip tie mounting tabs to a barbed t union. Both lines run to t union and the bottom of the union is left open when not in use but prior to filling I pipe clamp a plastic cap to barbed output then fill bumper through hole on top that is seal with a rubber expanding pipe stopper. When I get to the camp site I take cap off of the T union and clamp on a 1/4 turn ball valve with approx 20" of hose that allows me to control water flow and wash up. Bumper is sealed so well I have to remember to vent the stopper to release the vacuum. Prior to leaving I simply reseal stopper and change the ball valve out for the plastic cap on the T union and off I go. I have used it approx 3 nights in a row and never ran out of water for hand washing and dish washing and I read somewhere it holds approx 7-9 gallons. I plan on testing the volume more accurately soon. I will post back when done with that. Hope this helps.

I have the GenRight auxilliary fuel tank in that location. Carrying 20 gallons of fuel is noticeable, manageable but noticeble, when in motion. To unload the weight as soon as possible, I run that tank dry before switching to the primary tank. I'm not sure that carrying water in that location would be ideal, as it would not be emptied as quickly. For water, I've got the FrontRunner upright tank (10.54 gallons) directly behind the back seat. It puts the weight a bit higher, but it's right over the rear axle.

Thanks for the data point
This pic from genright shows it well, and it's almost exactly what I had been thinking of doing for water.

I have to imagine they spent a lot of time trying to maximize it's size, which is why it's such a complicated shape.

Other than making a custom shape water-tank, it's hard to imagine I'll be able to fit 20 gal in that space. Hmm.
I don't think 10 gal is enough for my needs, but 15 should be.
EDIT: Again, I need to run a tape measure over a JK. It would be interesting to try and stuff something like this up under there. http://www.frontrunneroutfitters.com/Water-Solutions/FRONT-RUNNER-WATER-TANK-60L-p296.html

Would love to see pictures of this setup. Thanks.
Stock Bumper Water Tank
Here is the plug I used. A basic small pipe expanding rubber plug.
Here is the plastic Elbow I used to tap into the bumper. There are two of these one on each side to allow gravity feed no matter angle of bumper.
The Vinyl Tube from each side then run down sides of bumper like this on the
Driver:
Passenger (Sorry for the bad rotation it loaded like this and I can't figure out how to orient it properly):
The hose is mounted to back of the bumper using zip ties and mounting squares like this:
They run to this brass T:
The output of the T remains open to allow air flow and prevent mold or smells building up inside the bumper. I made a small cap I attach to the bottom of the T when I put water in it. No images of that. When at camp I put a tube with a 1/4 turn ball valve to drain water. again no images of that but those two pieces are the easiest to imagine. If needed I can shoot those just being lazy!
I hope this helps out. If you have any questions let me know!

10 Gal or 40 Liters, not bad for something that fits in behind your seats!

Probably not. If you are going on an extended trip, you could simply remove the back seats. More space, less weight. I could use one in my XJ, but the same problem with the seats would happen. The bottom flips FWD into that space. They also sell the big bags too... I have heard good things about those.

^^Four of these on each side = 16 gallons of water.
