I'm wanting to fit a high tensile alloy bullbar weighing 46kgs. I would have a winch weighing 45 Kgs and a LED light bar weighing 8 kgs. I will also have 350kgs on tow ball weight (from a caravan) and roof racks carrying a Portabote weighing 35kgs. My wife and I weigh about 180kgs. Does the jeep GVWR allow this weight?? I heard the GVWR is 2947kg and the vehicle is 2307kgs without extras. Model is MY14. Doesn't look like much carrying capacity? Is this right???
