It does look a little light on the front axle as the towbar was to far back and had to much purchase on the truck and that trailer had too much deck in front of the bogie , fixed that know . In OZ we are allowed 6(ton) on the steer , 9ton on a single drive axle (if the truck has a 15ton gvm) , 16.5ton on the trailer bogie = 6+9+16.5=31.5ton . The rear tractor in the photo weighs around 4.5ton and the other two around 3.25ton each=11ton . The truck weighs 6ton and the trailer weighs 3.5ton=20.5ton all up . Take 20.5ton from my allowed 31.5ton GCM and that leaves 11ton to spare . GVM=Gross vehicle mass and GCM=Gross combined mass . Perish the thought i would ever run heavy....not like when i used to pull two trailers full of wheat with my old White 4000 with a combined weight of 100ton sshhhhh.
