Notes:
(i) When measuring the noseweight it is
important that the caravan is fully loaded.
Do not place extra items indiscriminately
into the caravan after this adjustment has
been made.
(ii) The caravan is intended to be towed
slightly nose heavy. The nose weight can be
adjusted by distribution of the load within
the caravan. The nose weight should be
approximately 7% of the actual laden weight
(but not greater than the hitch capacity) and
at the same time suit the towing vehicle. See
sectiononMeasurementofNoseWeight.
(iii) It is not recommended that you tow with
just a battery, spare wheel and gas bottles
as this may exceed the the permitted nose
weight. Additional payload must be placed
behind the axle to compensate for this.
TOWING VEHICLE TERMS

a full tank of fuel, with an adequate supply of
liquids incidental to the vehicles propulsion,
without driver or passengers, without any load
except loose tools and equipment with which
the vehicle is normally provided and without
any towing bracket.
