Ball Weight
When loading your caravan, the ideal ball weight once loaded is approximately 10% of the total weight of the
caravan. Use a ball weight scale to identify the ball weight and load the caravan in a manner that achieves the desired
10%. Ideally, once loaded the first time, take the caravan to a weigh bridge, and measure the total weight loaded
including the weight on the jockey wheel. When the total weight is known, adjust the load locations to meet the
desired 10%.
Effects of Weight Distribution
The distribution of weight in a caravan can influence the handling and performance of the van. Overloading the front
or rear may cause adverse handling and sway. Additionally, overloading the front or back can induce a pendulum
effect that can cause dangerous sway and cause an accident.
Tyre Pressures
Tyre pressures have a large effect on the handling of your caravan. Tyres that are under the recommended pressure
for the caravans’ actual weight can cause a dangerous sway. It is important to follow the correct pressure guide.
The guide below indicates pressure for the ATM which includes ball weight of 10%. Pressures are cold inflation
applicable to the standard Goodride 265/75R16 tyres fitted.
