Load Distribution
When heading away on your next big adventure it is important to load your camper correctly to
distribute weight evenly and achieve a suitable ball weight load and prevent loading in a manner that
can cause a caravan to sway and/or roll excessively left and right. The optimum ball weight on a
caravan is between 8% and 12% of the total camper weight.
WARNING: BALL LOADING (DOWNWARD LOAD ON TOW HITCH) MUST NOT EXCEED 350KG
OR THE MAXIMUM ALLOWABLE LOAD BY THE VEHICLE MANUFACTURER OR TOW BAR RATING,
WHICH EVER IS THE LOWEST.
Exceeding these limits may result in an accident, causing property damage and/or serious injury or
death.
• Always load both sides of the camper evenly
• Load heavy items low and directly over the axle.
• Secure all items to prevent damage to the camper during travel.
• Consider water tank levels and how they may affect the balance front and back and the percentage
of ball weight.
• Heavy cooking equipment should be stored in lower cupboards.
• Tinned and bottled food for cooking etc. should be stored in the pantry drawer.
• Never load in a manner that causes the ball weight to exceed the limit of the tow vehicle.

Electrical System
Batteries
The Simpson Camper trailer is fitted with 2 x 120 Ah AGM batteries. These batteries are designed to
be maintained at voltages between 12.0 V and 14.4 V. Should the batteries become discharged below
12.0 V, they will begin to degrade. The longer they are left discharged or the more times they are
discharged below this point, the less likely they will be to hold charge.
Battery charger
The Simpson comes fitted with the Projecta 25 A battery charger. This is solely a 240 V charger, it will
only work when the camper is plugged into shore power. It will comes preset, there is no need to
change the settings in the charger.
The Projecta charger has a built in recondition mode, which is recommended to run if the batteries
get below 12.0 V. This will balance the charge across the battery cells and help return the battery to
full health. It will not be able to give full health the deeply damaged batteries.
For all charger instructions, please see the manual in your camper or here
https://www.projecta.com.au/products/IC25/intellicharge-25a-bat-chgr
Solar
The Simpson comes with a 200 A free standing solar panel. This is designed to plug into the Anderson
plug on the drawbar. It has a built-in solar regulator and is plug and play.
There is a circuit breaker for the Anderson connection on the control panel. If the solar panel does not
recognise or charge the batteries, check this breaker to ensure that it has not tripped.
Mains Power
The Simpson comes standard with a 15 A input on the side of the camper to allow mains power to be
connected directly to the electrical system. This 15 A input has a larger earth connection than a
standard home plug and requires the use of a specialised 15 A extension lead which will have the
larger earth pin on both ends. If connecting the van to mains power point where a 15 A power point
is not available, you must use a 10 A -15 A adaptor with safety switch. These are available from most
camping or hardware stores.
The RCD safety switch for the 240 V circuits is located on the outside end of the main bed.
240 V mains power is lethal, failing to use an adaptor can result in serious injury or death.

Water system
The Simpson is fitted with 1 x 100L Foodgrade stainless steel water tank. The tank has a bung and tap
on the bottom for easy draining and rinsing.
The water tank filler is closer to the rear of the trailer. The filler is equipped with a breather hole which
will allow the air to escape the tank while the water is going in. If this hole is blocked, water will not
be able to enter the tank. The tank is full when water comes out of the breather hole.
The camper does not have a grey water tank fitted, please follow all instructions from Caravan Park
management/National Parks officers regarding the management of grey water.
Water Pump
The water pump will need to be switched on using the push button on the control panel. It may make
a noise when initially turned on with all taps closed to pressurise the system, but this should shut off
quickly. If the pump continues to run with all taps closed, this can indicate a leak and requires
investigation and rectification.
The water pump will automatically turn on when a tap is opened and will shut off shortly after the tap
is closed. It may turn on and off quickly a few times to fully pressurise the system, this is totally normal.
If the water pump is cycling on and off and the system has been thoroughly inspected for leaks with
nothing found, please contact the service department for more instructions.

Country Comfort Hot Water System
The Simpson camper comes with the Country Comfort portable LPG hot water system as a standard
inclusion. This is designed to work with the gas and water fittings on the drawbar of the camper to
provide a hot shower for use in the ensuite.
The Country Comfort hot water system is activated by water pressure, without water pressure it will
not operate. You need to ensure that the water tank being drawn from is full enough to provide a
consistent flow of water to the hot water system.
Full user manual and instructions can be found in the box or here,
https://countrycomfortwaterheater.com.au/collections/shower-packages/products/country-
comfort-portable-lpg-water-heater
Inside the hot water system box you will find hoses and fittings to connect the hot water system to
the water connection on your drawbar. There will not be a gas hose inside the box, the hose required
to connect the hot water system is in the draw under the stovetop of your slide out kitchen.
All adjustments and maintenance must only be carried out by an authorised person. The
installation of all gas and combustions appliances MUST comply with the standards in force.
Carbon Monoxide warning - This appliance is designed for outdoor use only and must be used
in well ventilated areas. Use in enclosed areas, including inside the camper annex, may result in injury
or death.

Braking Systems
Electric Brakes
The Simpson comes fitted with electric brakes which require a brake controller installed into the
towing vehicle that can be controlled from the driver’s seat. There are many systems available which
can either be permanently installed into the tow vehicle or Bluetooth units that are mounted to the
trailer and have a remote to control from the driver’s position. You must have a brake controller
installed in the vehicle or a Bluetooth unit on the day of handover otherwise the camper will not be
released to you.
Electric trailer brakes are designed to assist your vehicle brakes to stop in a safe and effective manner.
It is important that both your vehicle and the trailer are serviced regularly. The trailer brakes will have
a run-in period that will vary trailer to trailer, but it is important to have the trailer brakes inspected
and adjusted by a qualified professional in line with the maintenance schedule.
Trailer Plug Wiring
The Simpson comes fitted standard with a 7-pin flat trailer plug.
If a different plug configuration has been requested, please reach out to your local showroom or the
service department to obtain a copy of the wiring diagram.
Anderson Plug
The Simpson is fitted with an Anderson connection at the drawbar. This is wired directly to the
batteries through a circuit breaker inside the water tank change over compartment. This is designed
to run all regulated sources of charging to the batteries and can also be utilised as a power output if
required.
To adequately charge from your vehicle, you will need to have a DC-DC charger installed into your
vehicle. Without this, you will receive some charge, but it will rarely be enough to charge the batteries
to capacity.

Handbrake
The handbrake is operated mechanically by means of a cable. The cable attaches to the backing plate
and when the handbrake is applied the cable creates a force on the primary and secondary brake shoe.
This causes them to spread until they make contact with the brake drum surface.
The cable adjuster needs to provide enough tension that the handbrake is 1/3 raised when the camper
is unloaded. Once the camper is loaded, test and adjust if necessary. Insufficiently adjusted handbrake
will still allow the camper to move when the handbrake is fully raised.
It is very important to always use wheel chocks and levelling ramps, do not rely solely on the
handbrake even if on a level surface.
