This is the complete guide to heavy towing with a 4X4 wagon like a Landcruiser or a 4X4 ute like a Ranger.
In this report: The definitions and what they mean:
* Tare weight
* Kerb weight
* GVM - gross vehicle mass
* ATM - aggregate trailer mass
* Towball download
* GCM - gross combination mass
* Payload capacity
I also discuss the towing 'arms race' in which people think it's OK to tow a 3500kg trailer with a vehicle that weights 2500kg (ish) - and this is often a very bad idea, in my view.
I'll talk you through the payload limitations in the common vehicles and also discuss how you can actually measure your critical weights using a public weighbridge, to ensure you're not driving overloaded - which has important safety, legal and insurance implications.
Also discussed: GVM upgrades and warranty, and the effect of adding accessories on your payload capacity.
