It's been absolutely brilliant and I have had many "tours" of the set-up from interested campers. I probably could have sold it many times but it's just too good.
After a couple of trips away, it was evident that some things had to change. The water system needed an overhaul as the water containers ended up being too small in the space under the sink. We ended up taking additional water containers which only took up space elsewhere.
With that in mind, I sourced a couple of 53 lite rotational moulded drinking standard water tanks. The dimensions of the tanks allowed them to fit perfectly under the deck of the trailer between cross members. With the assistance of my brother in law, we made up a few "hangars" and a couple of frames to support the tank beneath the deck. Once I'd decided where the fittings needed to go, I took the tanks back to the manufacturer and they spun welded in some plastic fittings.
This is a 1/2" fitting spin welded into the water tank
Once the tanks were secured beneath the trailer, I installed some drawers under the sink using some off-cuts from the cabinets. I found some drawers with runners from an old bathroom vanity and modified the drawers to fit the width. Once these were completed, I connected up a basic water meter to provide an indication of the water level in both the fresh water and grey water tanks.
Removing the water tanks opened up the space in the galley beneath the sink.
