INTRODUCTION
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.
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 and
prevent loading in a manner that can cause a camper to sway and/or roll excessively left and right. The optimum ball
weight on a caravan is between 9 and 11% of the total camper weight.
Terminology & Abbreviations
Ball Weight: The downward load exerted on the tow point of the vehicle by the trailer
Tare Weight: The total weight of the unoccupied, unladen trailer ready for use with all included fitments from the
supplier. Empty water tanks.
ATM (Aggregate Trailer Mass): The total mass of the laden trailer when carrying the maximum load recommended by
the manufacturer. This includes any mass imposed upon the drawing vehicle when the combination vehicle is resting
on the horizontal supporting plane.
GTM (Gross Trailer Mass): The mass transmitted to the ground by the axle or axles of the trailer when coupled to a
drawing vehicle and carrying its' maximum load approximately uniformly distributed over the load bearing area.
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 centreline of the vehicle.
Positive toe, or toe in, is the front of the wheel pointing towards the centreline 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 millimetres at the front of the tyre from the chassis rail.

How to Hitch your coupling
Here is a short guide on how to safely use your coupling to couple and uncouple the
trailer from the towing vehicle.
Make sure the handbrake is applied prior to coupling and uncoupling.

Make sure the dust cap is securely connected to the bump cover. This is done by locating the rear lip on the
dust cap onto the groove of the bump cover and then pushing it in a downward motion until the dust cover is
secure (there should be a slight click when it has been assembled correctly) Test if the dust cover is connected
to the bump cover by applying a slight upward force to the dust cover, it shouldn’t separate.
This procedure should be applied if you are uncoupling or coupling up.

Coupling
STEP 1
Push down the button (1) and push the locking mechanism back (2). When the locking mechanism (2) is all
the way back, release the button (1) locking the plate in place
STEP 2
Offer up the tow pin to the coupling making sure the tow pin cover is removed and there is no visible debris on
it. Locking plate should be in unlocked position as shown. Lower the coupling onto the tow pin.
