We purchased a Smarttek 6 gas hot water system to replace our Coleman Hot Water On Demand which failed.
It has been setup with a Singflo 4.3lpm 12v pump to provide pressurised water. We have setup hoses to drawer water from a 20L jerry can, or from any water source via longer hoses.
Gas comes from our gas bottles mounted on the trailer, while 12v power comes from a socket mounted on the side of the trailer.
We have bought the tripod which makes it easier to locate where we want it, along with the 5m shower hose. The new shower head is much easier to turn on and off than the original model.
We also have the quick connect fittings which makes it much easier to setup.
