It should never weigh more than 1,500 lbs. (680 kg) under normal driving conditions. It should never weigh more than 1,000 lbs. (450 kg)when driven on long grades at high ambient temperatures. But even that can be tooheavy. It depends on how you plan to use your rig. For example, speed, altitude, road grades, outside temperature and how much your vehicle is used to pull B trailer are all important. And,it can also depend on any special equipment that you have onyour vehicle.
