Diesel Design

Fuel Tank

The S2C Chassis comes with a 35-, 60-, 65- or 100-gallon rectangular steel fuel tank mounted between the rails with left- or right-hand fill for increased safety and reduced fuel stops.

Lowered Engine Position

A lowered engine position provides a flat floor in the cockpit area, enabling drivers to safely move from cockpit to passenger area without having to step over a “doghouse.”
