The gross combination weight rating (also Gross Combination Mass and maximum authorised mass), which can be abbreviated to GCM, MAM, GCWR is the maximum allowable combined mass of a towing roadvehicle, passengers and cargo in the tow vehicle, plus the mass of the trailer and cargo in the trailer. This rating is set by the vehicle manufacturer.
When used with trains in the UK, the GCWR is also known as the gross train weight (GTW). The GCM is a function of the torque output of the engine, the capacity and ratios of the transmission, the capacity of the driving axles and tyres, the capacity of the radiator, and the ability of the chassis to withstand that powertrain torque.
GCWR primarily includes the powertrain's capabilities. Any of the powertrain's components, or combinations of, may create the weakest link in the powertrain. Mechanically, the differential gear ratio is not necessarily a weak link, but rather a ratio of power reduction or increase to the wheels depending on the ratio. A differential ratio of 3.42:1 will cause the engine and transmission to work harder than if the ratio was 4.10:1 with the same amount of weight hauled or towed. The tow vehicle will still move the weight regardless of the differential gear ratio. But a lower transmission gear may have to be used move the weight, therefore increasing engine RPM, and fuel cost, and may increase additional stress on the engine and/or transmission, therefore increasing the risk of premature wear and breakdowns. It may be noted that two identical vehicles with the only mechanical difference being the gear ratio will have different GCWRs and maximum towing capacities.

How to couple a tandem truck trailer combination with Duo Matic system Trucker DIY
A truck or lorry is a motor vehicle designed to transport cargo. Trucks vary greatly in size, power, and configuration; smaller varieties may be mechanically similar to some automobiles. Commercial trucks can be very large and powerful, and may be configured to mount specialized equipment, such as in the case of fire trucks, concrete mixers, and suction excavators.
Modern trucks are largely powered by diesel engines, although small to medium size trucks with gasoline engines exist in the US, Canada, and Mexico. In the European Union, vehicles with a gross combination mass of up to 3.5 t (7,700 lb) are known as light commercial vehicles, and those over as large goods vehicles.

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.
