just got 3 photos as its raining outside
here is the van from left side, upright 400lt tank on the middle of the van, Storm, some shelf over the tank,
equipment is fixed with the bungee, I have a water pump inside the water tank and swith for it on the right side, it fills my storm in minutes, waste water goes to the other tank that is behind.
because I have two sliding doors I did a shelf for everyday essentials
and here is the back, shelf on the left with tools, reels and waste water tank below that is not visible on the photo
wand is on the front of the waste tank bellow, just across the van
so, DIY is the best option as you can make a shelfs, reels and more just as you need it, as it always depends what stuff you have
