DRW stands for
Dual Rear Wheel. It refers to a truck configuration where there are two wheels on each side of the rear axle, instead of the single wheel configuration (SRW - Single Rear Wheel). This is common in heavier-duty trucks, pickups, and vans, as the dual rear wheels provide significantly increased load-carrying capacity and better traction.
So "DRW diesel" simply means a truck with a dual rear wheel configuration and a diesel engine. The diesel engine provides additional power and torque, making it well-suited for the heavier loads a DRW truck is designed to handle.
