I fitted this shelf above the gas cupboard door. It’s strong enough to take the weight of the levelling wedges. A hole was drilled through it to accomodate the pump and water pipe. The little enclosed bit below the 12v socket takes the adaptors for the Gaslow system. I got the French/Italian one and the european one. Bit pricey at about £14 each but probably worth it. The water can for the kitchen sink fits in front of the gas locker. I had some of the shower floor tiles left over so I used them to line the floor where the water containers are going to live. Saves having a soggy carpet…
