Ball Weight
When loading your camper, the generally accepted tow ball weight once loaded is around 10% of the
total weight of the caravan. Use a ball weight scale to identify the ball weight and load the camper in a
manner that achieves the desired weight. 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 balance considering 10% is the generally
accepted benchmark.
Effects of Weight Distribution
The distribution of weight in a camper can influence the handling and performance. 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.
