Weight Distributing: Weight distribution hitches add spring bars to the hitch system which are used to apply leverage between the tow vehicle and the trailer. This leverage transfers the load sitting on the rear of the vehicle to all the axles of the vehicle and trailer. With the trailer tongue and rear cargo load distributed between the axles, the vehicle is leveled off and performance is greatly increased. Weight distributing systems should be used any time the trailer weighs more than 50% of the vehicle weight.
Almost all mid-size SUV's have 3500 lbs capacity, but they are further rated for 4500-5000 with a weight distributing hitch. My Cherokee tows my aluminum trailer with a 911 just fine, but I have to load all my tools and spare tires on the Jeep..and be mindful of weight distribution of the trailer. It's very doable and safe enough. I'm not familiar with the X3, but it seems even smaller than my Cherokee which has enough torque to get things rolling.
