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
