These 6 Wheelers were once relatively common. Let’s go back to the ‘80. At that time, there was a gap in the Australian vehicle market. The buyers had to choose between a Japanese 4x4 pickup truck (1-ton payload) or a big 4x4 truck (from Mercedes and others). An Australian car license covers vehicles up to 4500 kg. So people started to look for more payload and longer trays on their utes (pickups). These days, this gap in the Australia vehicle market does no longer exist. But there are still companies producing these conversions, mainly for mining companies.
