LOAD TABLE 1 - BALL TO CAR REAR AXLE LOAD
This calculator looks at the car's wheelbase, the distance from the rear axle of the car to the ball on the hitch and the actual or proposed load on the ball from the trailer.
Your Car’s Wheelbase	Distance from Car’s Front Axle to Rear Axle		Millimetres
Your Car’s Tow Bar Overhang	Distance from Rear Axle to Tow Ball		Millimetres
Actual or planned Ball load	Tow Ball Load from Trailer		Kilograms
Calculated New Load on Car Rear Axle	Result will need to added to, or substracted from known existing Trailer Ball Load		Kilograms

LOAD TABLE 2 - MULTIPLIER FOR BALL TO CAR REAR AXLE LOAD
This calculator looks at the same measurements as Table 1. By knowing the car's wheelbase and the hitch overhang, you can determine a multiplier for your car.
Your Car’s Wheelbase	Distance from Car’s Front Axle to Rear Axle		Millimetres
Your Car’s Tow Bar Overhang	Distance from Car’s Rear Axle to Tow Ball		Millimetres
Multiplier of Ball Load to Car Rear Axle	Result - Imapct of ball load on Rear Axle of car		Multiplier

LOAD TABLE 3 - MOVING ITEMS IN THE TRAILER TO CHANGE THE BALL & TRAILER AXLE LOAD
This calculator asks for the load of the item you are adding or removing (show as negative). Then, by knowing how far the trailer axle is from the ball and where the item is to be added or removed, the impact of the change on the ball load and the trailer axle can be calculated.
Weight of the Item being added OR removed	Show as negative if item is being removed		Kilograms
Distance from Trailer Axle to the Ball			Millimetres
Distance in front of Trailer Axle of Item	Show as negative if item is behind the axle.		Millimetres
Calculated impact on Ball Load	Result will need to be added to, or subtracted from, known existing Trailer Ball Load		Kilograms
Calculated Imapct on Trailer Axle	Result will need to be added to, or subtracted from, known existing Trailer Axle Load		Kilograms
IMPACT ON CAR REAR AXLE LOAD
Just as Table 3 provided some insight into how removing or adding items somewhere in the trailer can make a difference, Table 4 allows you to see the impact of removing or adding items in, and on, the car itself.
Multiplier of Ball Load to Car Rear Axle	Use ‘Load Table 2 - Multiplier for Ball to Car Rear Axle Load’ to calculate multiplier for your Car		Multiplier
Calculated new Ball Load impact on Car Rear Axle	To be added to, or subtracted from, known existing Car Rear Axle Load		Kilograms

LOAD TABLE 4 - MOVING ITEMS IN THE CAR TO CHANGE CAR AXLE LOADS
Just as Table 3 provided some insight into how removing or adding items somewhere in the trailer can make a difference, Table 4 allows you to see the impact of removing or adding items in, and on, the car itself.
For changes to Ball Load use ‘Load Table 1 - Ball to Car Rear Axle Load’
Weight of the Item being added OR removed	Show as negative if Item is being removed		Kilograms
Your Car’s Wheelbase	Distance from Car’s Front Axle to Rear Axle		Millimetres
Distance behind Car Rear Axle of Item	Show as negative if Item is in front of the axle		Millimetres
Calculated impact on Car Rear Axle	Result will need to be added to, or subtracted from, known existing Rear Axle Load		Kilograms
Calculated impact on Car Front Axle	Result will need be added to, or subtracted from, known existing Front Axle Load.		Kilograms
