Wheels and Tyres
Highway
Your caravan is fied with 16” wheels and 265/75 R16 Goodride Tyres. The tyres are a “Light Truck” tyre with a mud
terrain tread and a maximum load rang on single axle of 1550kg at 80psi.
Recommended highway pressure at tare weight of the caravan is 50psi
Recommended highway pressure at ATM of 3000kg is 72psi
Off Road
Off road driving requires lower tyre pressures and lower speeds. When driving on rough and corrugated road, a reducon
of speed and controlled deflaon of tyres is required to protect the caravan and its suspension from damage. In extreme
circumstances tyre pressures may be reduced significantly. When lowering from highway pressure, a rule of thumb is to
reduce your speed by the same percentage as the lowering of tyre pressure.
Because off road condions can vary greatly, you must lower your pressures and reduce speed unl vibraon and shock
through the suspension is at a moderate level to suit the condions you are experiencing, and the loaded weight of your
caravan.
WARNING: When returning to the highway or when increasing speed, you must reinflate the tyres to correct highway
pressures. Failure to reinflate can cause severe handling problems resulng in injury or death.
Suspension
Your camper is fied with quality independent trailing arm suspension with dual shock absorbers. This design is ideal for
the full range of use on and off road however, there are limitaons in prolonged use of corrugated and rough road.
Shock Absorbers & Bushes
The funcon of shock absorbers is to turn kinec energy into heat and dampen the rebound in the suspension to keep
the tyre in contact with the road. During prolonged periods on corrugated and rough roads it is possible to overheat
shock absorbers to the point of failure (shock fade). Best pracce is to take regular breaks and allow both the shock
absorbers and suspension bushes to cool. Overheang the bushes through prolonged driving on corrugaons can soen
the thermoplasc and cause premature wear and/or deformaon of the bush. On severely rough roads stop regularly up
to every hour to allow components to cool.
Hitch
Cruisemaster DO35
To ensure a long service life we recommend the following periodic maintenance procedures.
1. Always keep Tow Pin and Universal mang surfaces clean and lightly lubricated.
2. Check condion of Tow Pin O-Ring and replace if necessary (Part No. 18D-DO35-101).
3. Regularly lubricate grease points with mul-purpose grease.
4. Periodic adjustment of Sloed Nut & Pin may be required of coupling head loosens excessively and should
be a competent person.
5. Flush with clean water if locking mechanism does not open fully due to dirt ingress.
Ball Bearing Slides
To lubricate and protect from corrosion the ball bearing slides should be lubricated with a small amount of general
purpose grease every 6 months.
