The problem with staying in a National Park in most of the new breed of ensuite pop-top or fully-featured off-road caravans is that a standard toilet cassette will run out of waste space before you run out of interest.
The average RV gravity chemical cassette/caddy holds less than 20 litres of waste, which (according to experts in the industry) is only good for around three days’ normal use by a couple.
So as chemical waste cannot be buried in off-road situations, septic systems or pit toilets, you have to cross your legs and wait until you find the next official town dump point, or go bush. And as these official dump points are often few and far between in remote areas, many people find themselves planning their trip around their location.
However Caloundra-based Australian Off-Road has come to the rescue.
With the demise of the vacuum toilet system, previously used by AOR and many other Australian manufacturers, the Queensland company has applied proven marine technology to produce a functional and robust system suitable for longer, extreme off-road use.
By combining a marine-type macerator toilet with a 35-litre dedicated flushing tank and a 60-litre black water holding tank, AOR's system offers three times the storage capacity of a regular cassette, which equates to around 10 days before the tank needs to be emptied.
The chemical-free system uses an easily replaced or repaired 12-volt diaphragm pump to remove waste via a 40mm hose to a dump point or waste container and the whole system can be flushed through with fresh water.
The new Nomad Dual Evacuation toilet system is now standard on AOR’s Quantum pop-top and Matrix off-road caravan and will be standard on the company’s new full-size off-road Voyager caravan when it's released in June next year.
