Brooksy, and Struth, you blokes should b e disqualified!
My rig is nothing out of the ordinary, a couple of things I have done that I really like are
rear tail gate storage hatch for my recovery gear. its accessible, out of sight, always on board and takes up no cargo space anywhere else

hatch closed

slam latches, one finger operation

all my recovery gear, tyre deflator, snatch strap, tree trunk protector, 20m winch extension strap, bow shackles, snatch block, winch control, puncture kit, glove, drag chain etc
water bottle for camping. easy to fill a drink bottle from, wash hands, or get water for cooking.
Fill the bottle in the car, one handed operation, no tricky pumps etc, so it is always 'ON', it just uses gravity, simple idea and I set it up with about $10 bucks of gear from bunnings and a 20l water jerry. It works a treat

hose hanging up out of action

hold the end of the hose above water level, flow stopped

hold the end of the hose down below water level, water flows to fill pots, bottles, wash hands, fill up a dog etc
