PAYLOAD & GVM CALCULATOR

Maintain vehicle safety and legal compliance. Quantify the mass of every component, fluid, and furniture node to ensure your build remains within Gross Vehicle Mass (GVM) limits.

Stability Tip

Keep heavy items like water tanks and battery banks as low as possible and ideally between the axles to maintain a lower center of gravity and improve handling.

The 3.5t Threshold

Most UK van conversions are built on 3,500kg (3.5t) chassis. This limit is critical: exceeding it is not only illegal but invalidates your insurance and significantly increases braking distances.

Dynamic Distribution

Mass is not just about total weight; it's about distribution. Unbalanced loads (e.g., placing all water tanks and batteries on one side) can lead to uneven suspension wear and poor handling.
