Why are refrigerated vehicles more expensive than ambient (curtain side) vehicles?

Refrigerated vehicles are more expensive than ambient vehicles because they require specialised equipment to maintain a specific temperature range during transport. This includes refrigeration units, insulation, monitoring equipment and other components that are designed to keep the load area at a consistent temperature. Additionally, the cost of fuel is typically higher for refrigerated vehicles due to the added weight and increased demand for power from the refrigeration unit.
