S2RV Engines

“Front-engine diesel” may conjure memories of the loud, sooty giants of the past. But the modern diesel delivers quiet, clean power and much better mileage than its predecessors. With horsepower ratings up to 360, Cummins engines provide durability and lower maintenance costs for the S2RV through an excellent balance of low-end torque and high-end acceleration. These electronic engines will deliver the performance you expect when you need it most, plus provide a lifetime of no-hassle maintenance.

Fuel Tank

The S2RV chassis comes with a 60- or 100-gallon rectangular steel fuel tank mounted between the rails with left- or right-hand fill for increased safety and reduced fuel stops.

DEF Tank

The S2RV's 10-gallon DEF tank is located under the cab for refill convenience.


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.”
