Legendary RV personality “Mr 4x4” Pat Callinan has given his honest thoughts after installing Aus J’s Duoetto MK2 12V/240V water heater and EZY RV exterior shower outlet on his 4WD.

  • No more sandy, dirty dog in the van!

    I found Aus J’s Duoetto MK2 12v/240v 10L water heater and knew it would be a good fit for my VW Transporter. The thought that has gone into the design was impressive.

    Jay is very easy-going and helpful – he gave incredible service and help in the installation. I am very happy with the final product, which I put under a fold-down lid in a cargo space at the rear of my van.

  • Great product for extreme outback conditions

    The fact that the Duoetto can switch between 12V and 240V is a major advantage for our fit-outs. It means our customers can travel to remote areas and still have hot water available for cleaning, showering and other uses.

    We love that the Duoetto is an Australian-designed product, and the service from Jay has been outstanding.

  • The Duoetto fits beautifully into our custom Mercedes van fitouts

    Our customers love the value, cost-efficiency and simplicity of the system. It’s such a simple system to use. Also, by comparison, it is solid, quiet and has no exhaust compared to the similarly priced propane tankless water heaters.
