Caravan Broken Spring

Just was returning to Mt Isa from Cloncurry and came upon 2 Caravans parked on the left and just not quite off the lane by 200 mm out near Dingo Creek just about 2 klm from the Lake Julius T/O and 2 real bad black marks veering of the road behind the first one and when I seen that I knew this was not good, What had happened was the right rear spring decided to to be in 2 pieces instead of one and the right rear wheel was positioned in the center of the van and about 1.5 mts from the back underneath , I feel they were very lucky the van was a tandem as the front set kept it in line, they had Sat phone and had organised help , things like that can stuff up a good holiday and the Van is only 9 months old.
