ⓘUse the tray length for the flat deck only. Measure drawbar length from the front edge of the tray to the towball centre.
Example: top-view measurements
Tray length is measured along the flat deck. Drawbar length is measured horizontally from the front edge of the tray to the towball centre.
⚖ Load Distribution (4 Equal Quarters)
Enter the weight (kg) in each quarter of the tray. Quarter 1 is the front/towball end. Quarter 4 is the rear end.
