The XL Service Body has been designed with a low roll centre – the imaginary front to rear axis by which your vehicle rolls when cornering. For example: a racing car has a low roll centre – the track is wide and the vehicle height is low. This combination offers great road handling (and fuel economy) compared to a higher vehicle or a vehicle with its load mounted a long way above the ground. Imagine two identical vehicles, one loaded with 500kgs on top of the cab, and the other with the 500kgs mounted 95mm above the chassis rails. Which one corners more easily and safely? The one with the load closest to the ground will be safer to drive and provide better handling, especially during lane changing and cornering.
