How does the length of the rear overhang affect load capacity and drivability?
The longer the overhang, the more weight will be distributed to the rear of the vehicle. When payload volume is more important than capacity, you want a better distribution of weight. In other words, more area in the back must be used to distribute the weight evenly. As far as drivability is concerned, the longer the vehicle, the more you will have to compensate for maneuverability in tight turns.
