Geoff,I agree with Craig we broke the hitch where the w.b.rods slip into the part near tow ball,we were heading to Koonalda station 17 ks off the main road , carried on to albany,perth coast trip around to albany mt barker before heading back to Adelaide. got back to adelaide went to adelaide spring steel who makes them and was told to remove them before reversing or going off road,
we now keep them in the shed ,
we towed with bt50 well over 10,000 klms on dirt and highway (110klms) not had a problem.I feel safe without them otherwise i would replace them my life is valuable,
regards Shiraz
