The vocational truck market is highly competitive as the manufacturers try to continuously improve their models in order to keep the truckers satisfied. But apart from the engines, chassis and payloads which play a major role in the trucking industry, there is one thing that is more important than anything else. And that’s the vehicle’s reliability.

The truck is available in two versions including the VHD Standard and the VHD 430 which is available with both Day and Sleeper cab configurations.
