Hi Fizzie, I had been towing my 8m boat on a triaxle trailer from home to Tin Can Bay about 1,5 hour run at 50kph behind my 3,2lt diesel Narvara dualcab for around 6 to 7 years no worries, got pulled up, put the boat and trailer on the scales she went 4,1ton, tug tow limit 1,8ton, I wonder why they were nice to me, Them days rules never bothered me, I was a farmer towed heaver loads around the farm every day, After that enlightenment to the real world I only run legal now, Hence the small van and 5m tinny, Craig
