Gas Bottle Contents Gauge

We spotted these on an A'liner on a recent stay at Pin Cushion Caravan Park at Maroochydore, Queensland.  Very easy to retrofit to most A'vans with no need to use a gas fitter as it is just a plug in accessory. Best to check this if you are in doubt though just in case it's not legal in your state. The A'vanner bought his at his local gas centre for under $40.00.
