Introduction
WELCOME TO MDC
Off road caravanning is a rewarding way to travel and see our great country. Owning an MDC Caravan
will afford you the opportunity to travel to remote places and stay in comfort. It is the intention of
MDC for you tohave the best possible owner experience and enjoy the great outdoors.
Terminology & Abbreviations
Tare Weight: The total weight of the trailer (load on tyres plus coupling load) with all options and
fittings as supplied by the manufacturer, with empty water tanks, excluding fluids not essential for
operation on public roads, and without luggage or personal effects.
ATM (Aggregate Trailer Mass) Rating: The total permissible mass of the Trailer. This includes the coupling
mass and whatever you add as payload (e.g. water, gas, luggage) up to the specified rating. The ATM Rating
must not be exceeded.
GTM (Gross Trailer Mass) Rating: The total permissible mass that can be supported by the wheels/ tyres of
the Trailer. This includes whatever you add as payload (e.g. water, gas, equipment, and luggage), but does
not include the mass supported by the tow vehicle. The GTM Rating must not be exceeded.
Caravans for illustration purposes only.

Ball Weight: The downward load exerted on the tow point of the vehicle by the trailer.
GCM: (Gross Combination Mass): This is the total allowable combined mass of tow vehicle and trailer as
determined by the tow vehicle manufacturer.
Camber: Camber angle is the measure in degrees of the difference between the wheel’s vertical
alignment perpendicular to the surface. If a wheel is perfectly perpendicular to the surface, its camber
would be 0 degrees. Camber is described as negative when the top of the tyre begins to tilt inward
towards the chassis rail.
Toe In/out: Negative toe, or toe out, is the front of the wheel pointing away from the centerline of the vehicle.
Positive toe, or toe in, is the front of the wheel pointing towards the centerline of the vehicle.
Toe can be measured in linear units, at the front or rear of the tyre, or as an angular deflection. In the case of
MDC products, the “toe in” is measured in millimeters at the front of the tyre from the chassis rail.
Tow vehicle and Trailer Compatibility
Your tow vehicle manufacturer has applied a maximum towing capacity to the vehicle which is the Aggregate
Trailer Mass (ATM) and a maximum Gross Combination Mass (GCM). These specifications MUST NOT be exceeded.
It is your responsibility to know, understand and follow these specifications. Vehicle manufacturers may also
specify or recommend “Weight Distribution Bars” when towing under certain conditions. You MUST ensure this is
compatible with the vehicle and trailer combination.
DANGER
DANGER – Exceeding manufacturer weight and combination limits can result in
loss of control leading to death or serious injury. Your tow vehicle and hitchmust be
rated for the Gross Vehicle Weight of the trailer.

Safety Information
WARNING–
Before using this product, you should read this manual, and those manuals supplied by component
manufacturers applicable to this product.
This manual is supplied as a reference to required maintenance of the product. Failure to use and maintain
the product in accordance with what is outlined in this manual may affect your warranty.
Incorrect and/or insufficient maintenance may cause product failure resulting in property loss, damage or injury or death.
Maintenance intervals are critical for normal use, extreme use may require shorter or additional maintenance intervals.
Manual content does not imply, express or other any warranty, the owner should read the limited warranty terms included in this
booklet.
MDC does not cover damage due to unauthorised modifications, misuse, abuse, incorrect assembly,
improper and irregular maintenance or accident or collision.
Before using this product, you should be certain your tow vehicle is suitably rated and equipped to tow the product safely and
legally. The trailer and vehicle pairing must we within the safe “Maximum Towing Capacity”, “Ball Weight Capacity” and “Gross
Combination Mass” as stated by the vehicle manufacturer.
This caravan is fitted with electric brakes and a “Breakaway System”. Requirements for breakaway systems can vary from
state to state. It is mandatory to supply a maintenance charge to the breakaway battery source while driving. You MUST
ensure this capability is fitted to your vehicle. The maintenance charge is supplied to the caravan via the Anderson plug on
the drawbar.
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 serious injury or death and/or property damage.
It is important to load your caravan correctly to distribute weight evenly and achieve a suitable ball
weight load andprevent loading in a manner that can cause a Caravan to sway and/or roll excessively left
and right. The industry optimum ball weight on a caravan is between 9 and 11% of the total Caravan
weight. MDC Caravans fit into this category and 10% should be used as the starting point.
Modifications to The Product
Gas Systems
The installed gas system on this product is an approved and certified installation. Any changes,
modifications or adjustment may render the system non-compliant and dangerous. Market Direct Group
Pty Ltd does not condone,recommend, or otherwise consent to any modifications, adjustment, addition
or tampering in any way with the installed gas system on any and all products.
Chassis
All MDC chassis are fully engineered and verified using Finite Element Analysis (FEA) software. This
ensures that the chassis for each model passes the relevant regulations and design rules as originally
provided to the customer. Any modification to the chassis or drawbar whatsoever (no matter how minor)
will inevitably change this – whetherit impacts the towing dynamics, expected loads and stress points,
safety chain attachment points, overall trailer length etc.
Market Direct Group Pty Ltd does not condone, recommend, or otherwise consent to any modifications,
adjustment, addition or tampering in any way with the drawbar, safety chains or safety chain
attachment points.

Jacking Your Caravan or Camper
Your trailer is fitted with purpose built jacking points and from January 2021 supplied with a suitable jack. An
appropriately rated bottle jack is an acceptable alternative, however when using the jacking point beneath the
trailing arm ensure the jack is of a retracted height that will fit under the jacking point when the tyre is deflated.
A suitably rated “High Lift” jack may be used on the jacking points on the side of the body behind the wheels
provided it has the correct positive engagement fitting to match the trailer. To ensure safe usage the following
must be followed:
•The jack is to be used on level firm ground wherever possible.
•The wheels of the trailer should be chocked, and no person should remain inside the trailer whilst it is
being jacked.
•No person should place any portion of their body under a trailer that is supported by a jack.
•The trailer should be attached to the towing vehicle whilst being jacked.
•When performing maintenance ensure suitably rated jack stands are used – do not rely on the trailer
being supported by the jack.

Electrical Safety
Warning
Failure To Follow These Instructions May Result In Death Or Serious Injury!
When working with electrical equipment or lithium batteries, have someone nearby in case of an
emergency.
Study and follow all the manufacturer’s specific precautions when using and servicing the battery and
connected appliances.
Wear eye protection and gloves.
Keep unit away from moist or damp areas.
Avoid dropping any metal tool or object on the battery. Doing so could create a spark or short circuit
which goes through the battery or another electrical tool that may create an explosion.
Warning
Shock Hazard! Keep Away From Children
Avoid moisture. Never expose unit to snow, water, etc.
Inverter Unit provides 230 VAC, treat the AC output socket the same as regular wall AC sockets at home.
Read and understand the information in the appliance manuals before operating this equipment
The 240v electrical system in your caravan has been certified by a trade qualified person. Under no circumstances

Vehicle Electrical Requirements
Brake Controller
All MDC campers and caravans require an electric brake controller to be fitted to the tow vehicle by law. There is
a wide range of controllers available that are suitable.
Correct Vehicle Wiring for MDC Caravans
To comply with national laws on breakaway systems, you must supply a maintenance charge to the
battery/batteries that power the system should it be activated. In all MDC products, the breakaway is powered by
the house batteries in the caravan. For this purpose and Anderson plug connection is fitted to all MDC caravans
on the drawbar. Your vehicle will need to be fitted with a power supply to a 50 amp Anderson plug near the
towbar so the trailer can be connected. The vehicle only needs to supply power while it is running so a voltage
sensitive relay or switching device may be used to protect the start battery when the car engine is stopped.

Trailer Lights
Plug Type – 12 Pin Flat (Not Negotiable)
Charging Camper/Caravan While Driving
Plug Type – 50 amp Anderson Plug.
Vehicle with or without smart alternator:
The Anderson plug can be connected to the start battery on the vehicle and should include the following to
protect the start battery.
1. 50-amp relay to stop power supply when vehicle is not running.
2. 50-amp fuse or circuit breaker at the battery
Notes: The Projecta IDC25L DC to DC controller fitted in your MDC trailer is programmed to favour the
solar panel input exclusively until it drops below a threshold voltage input. By providing accessory power
to the number 12 pin, the trigger for the IDC25L will be set off to take power from both the Anderson
plug and the solar panels. It will also trigger the IDC25L to activate the vehicle’s ECU to make the
alternator provide power to fully charge the multiple batteries in your Caravan.

Trail-Assure Electronic Stability Control System
As an added safety feature, your 15-year anniversary model caravan is fitted with a Trail-Assure BG-5000
electronic stability control system. This is an asymmetric braking system that uses onboard measuring
instruments to determine which wheel brakes to apply, and how often, to increase the stability of your caravan
while driving.
The BG-5000 has been factory fitted precisely with the controller module mounted in the front underneath
section of your caravan so that it can make reliable and precise measurements during a trip. It also features a
factory pre-set algorithm to sense off-road conditions and automatically disables the stability braking to avoid
nuisance brake applications in off-road conditions, minimizing unnecessary brake wear. The system will
automatically re-engage once you are back on the road.

Gas & Appliance Safety
Gas Certification
Your Caravan has been supplied gas tested and certified. Any additions or alterations to the gas
system must be performed by an authorized person and will require re-certification and testing.
Also note any alterations may affect your warranty on both the system and appliances.
General Safety
•Your Caravan may have a number of gas safety labels affixed throughout containing important
information. Allinstructions are to be followed and the labels shall not be removed for any reason.
•Make sure to close appliance valves before opening the cylinder valves.
•Where readily accessible, check connections at the appliances, regulator, hoses and cylinders
periodically forleaks with soapy water (or an equivalent) – this should be done every time a cylinder is
changed or at least annually.
CAUTION – the ammonia present in some soaps and detergents can react with brass fittings and
cause such fittingsto crack after a short period of time. Therefore, caution should be exercised
when using soap solutions on brass fittings and all connections should be rinsed thoroughly with
fresh water as soon as possible after the application of the soap solution.
•Never use a match or flame when checking leaks.
•Never use cooking appliances for comfort heating.
•In the event of a fire, immediately close cylinder valve if safe to do so.
•Appliances must not be altered without the authorisation of the manufacturer.
•In the event of an accidental gas leak, close cylinder valve and ventilate the area using a safe method
until the air is clear.
•Flexible hoses are used between the LP Gas Cylinder and regulator as well as between your slide-out
kitchen cooker (if fitted) and the gas bayonet. These flexible hoses are easily accessible and shall be
inspected regularlyby a competent person.
Gas Cylinder Safety
•LP Gas cylinders have a 10-year lifespan between inspection and re-certification. Always use gas
cylinders that
are within their compliance date.
•For drawbar mounted cylinders (if applicable), orient the cylinder relief valves of both cylinders
discharge awayfrom both the trailer and towing vehicle as shown.
•For gas cylinders stored in a dedicated LP Gas Locker ensure the locker is kept closed at all times
unlesschanging or operating the cylinders.
•Close cylinder valves when appliances are not in use or while refueling is in progress.
•Ensure cylinder valves are closed to prevent the unintended release of gas from a cylinder.
