i mount drinking water externally in a wire basket made for it-- just like u see on work trucks. On driver side of tub. (btw, jeep rescues hummer). Got it all @ Granger.
another shot showing how its placed. fill 3/4, drop in a block of ice and ur good to go, altho i duct tape the lid to avoud splash-loss. This way fresh water is always available, etc.
For possible fire supression, i mounted an old compressed-air powered extinguisher and is a nice source of pressurized water-- it'll shoot a stream of water over 40'. (super soaker?) Pressurize it w/ ur OBA. Helps as a trail side jeep wash. Got this one for $5 at a garage sale. Mounts to tire carrier. Here camping at Ellis Creek, Rubicon 7/07.
