GCWR (Gross Combination Weight Rating)
GCM is the maximum combined load of the tow vehicle and trailer, as specified by the tow vehicle manufacturer.
Never exceed this maximum weight limit.
Summary
The above will assist in tuning or trouble shooting handling problems with your towing combination but are not
the sole influences. Other items for consideration are:
• Wheel alignment on both vehicle and trailer.
• Wear and tear on:
- Suspension bushes
- Shock absorbers
- Springs
- Tires
• Tow vehicle tire size (Oversize tires)
• Extended hitches
• Distance between axle centre and hitch point
• Tow vehicle accessories (Weight distribution)
• Real life tow vehicle capability (Not all vehicles are created equal)
The purpose of this information is to help you to do a self-assessment and achieve a sound towing combination. If
you are not confident you can achieve this, you should consult an expert to assist.
