I have a Nissan D40 dual cab, with a DIY drawer system. I currently have a couple of jerrys of water sitting securely on top of the drawers, which I can siphon when required - but its a bit of a rigmerol (?). I'm thinking of getting a 1120x330x200 poly water tank and sit this across the drawers just behind the cab. The plan is to run some plumbing from the tank to the tail gate area and have a tap and hose fitting for easy access. I did a quick search here but couldn't find any similar thread. Is anyone able to give me some pointers on what I should and shouldn't do? cheers
