Rear-Engine Diesel Design

Rear-Engine Diesel Design

Rear-engine diesels provide a host of benefits, including more floor plan options, quieter interior environments, more comfortable rides, lower fuel costs and effortless hill climbing. You'll also appreciate the enhanced reliability of a diesel engine and the fewer maintenance stops.

Side-Mounted Radiators

Side-mounted radiators are available on our raised-rail designs with Cummins ISL engines. Like our rear-mounted radiators, this design features a variable-speed fan that automatically increases and decreases fan speed as needed to reduce noise and decrease power loss.

DRIVER’S SIDE DIESEL EXHAUST FLUID (DEF) TANK

Conveniently positioned near the diesel tank for quicker fill-ups, the DEF tank also features stamped brackets rather than formed sheet metal.

90-, 100- or 150-Gallon Fuel Tank
