The Underbelly - A Brian Morgan Design

The Underbelly is the the first truck-based bottom dumper of its kind — developed in New Zealand specifically for New Zealand conditions.

Until now, traditional bottom dumpers have only been available in trailers, with either a tipper body or a fifth wheel fitted to the towing truck. Conventional design has limited the possibility of a truck-based bottom dumper due to the reduced working width inside the chassis rails.

By removing a section of the chassis, the Underbelly achieves a full width tapered hopper on both a 6 and 8 wheelbase with no interference from the chassis rails, allowing for full spread of the load.
