I paid for the new tow bar I had made, fitted and engineered to 3.5 tons by a reputable company. They did a really nice job well worth the cost and I am very happy with it. Now I have multiple towing height options so wont be dragging the back end of a trailer along the road anymore. I will put a pick on here when I have worked out how to do it. I am not sure if I am allowed to put the name of the company on here but if anyone wants to know then msg me.
Chassisline in Toowoomba did the job, They were not afraid to touch the Perentie and I had a very good service experience with them. After having a good look at the way the rear end was constructed the comment was that it was much stronger than the stock chassis. It's all at least 4mm steel and well lapped into the original so quite happy to put 3 to 3.5 tons on it. Very helpful working with me in drawing up what I wanted and getting it to fit. The cost was just under 2 grand including GST but I had removed the Exhaust tail pipe, mud flaps and tied any wiring up out of the way to reduce the work they would need to do.
The chassis is drilled and tubes welded in for the bolts to go thru. They spoke the right language so I was happy for them to do it and I am well pleased with what has been done.DSCF3783.jpgDSCF3785.jpg There is a perpendicular stiffener on the inside. It's as solid as a rock.
