The reason the Draw Tite hitch part # 76194 can't be used with a weight distribution system is due to how it attaches to the vehicle. What we have found is that if it attaches along the bottom of the frame rails it can be used with a WD system, assuming the vehicle can handle it, but if it attaches to the back of the frame like this hitch it cannot be used with a WD. It just puts too much torque on a portion of the frame that is smaller so it can't handle the stress. view full answer...
