Choose Generic Template or Request a vehicle

If the manufacturer, range, or model you are looking for is not on the list, click on ‘Generic Template’ in any of the following screens to ‘build your own’ vehicle, by applying weights and dimensions values from a specification sheet.  Alternatively click ‘Request a Vehicle’ at the bottom of the selection screen and our support team will add your vehicle to our database.

Below ‘Trailer 1’, a set of sub tabs – ‘Length’, ‘Weights, ‘Equipment”, ‘Axles’ – appears.  Click the >> icon to view more tabs, for example, ‘Height’.


Add a body to the trailer

On the ‘Equipment’ tab, click ‘Add’ to open selection page.


Double click “Template Curtainsider/Tautliner” from within the ‘Body’ tab.


A Curtainsider/Tautliner body has been added to the trailer and the weight of the body has been added to the calculation beneath the drawing.  Note tare weight (Curb weight) of the vehicle, unladen trailer weight, gross vehicle weight rating (GVWR), weight distribution over each axle, the total truck weight and maximum payload achievable with this configuration.  The Permissible weights are the ‘lower of’ maximum weights allowed by the vehicle manufacturer and the legislation that has been applied to the calculation.


A set of sub tabs relating to the body appear, titled “Length”, “Weights”, “Height” and “Width”.


Use the ‘Length’ tab to adjust dimensions such as distance from ‘Back of cab’, the ‘Weights’ tab to specify body material weight, the ‘Height’ tab to adjust the height of the body, the ‘Width’ tab to adjust sidewall thickness.
