jeffmackb Posted July 19, 2013 Share Posted July 19, 2013 Yes, they built quiet a few 6x6. The Australian Defence Force had Mack Trucks Australia build them about 940 RM-6866RS trucks starting in about 1983.These trucks were Six Wheelers, the four rear wheels were dual wheels.

jeffmackb Posted July 20, 2013 Share Posted July 20, 2013 The second 'M' in 'DMM' designates a setback front axle arrangement.In 'RM' and 'FM' it is the setback front axle. But not in 'DM', because a 'DM', is a 'DM'. It needs a second 'M' to designate the setback front axle arrangement.You can have an 'RM' that is only a 6x4 or a 4x2 e.g. RM-685RS or an RM-685RTAs Jim has pointed out, It is the fourth number that designates all wheel drive e.g. RM-6856RS would be a 6x6, RM-6854RT would be a 4x4. 1 Quote Link to comment https://www.bigmacktrucks.com/topic/31966-6x6-maxidyne-dump-truck/#findComment-194891 Share on other sites More sharing options...
