Can a GWM Tank 300 tow a Australian Off Road Sierra?
"When matching the GWM Tank 300 with the Australian Off Road Sierra, we need to look beyond just the maximum towing capacity. The real story is often in the GCM (Gross Combination Mass) and the ball weight limits, which can catch out even experienced caravanners."
Yes, this is a legal match
The Tank 300 has a towing capacity of 3000kg, which comfortably handles the Sierra (1800kg).

Always check your compliance plate
Online databases (including Redbook) use factory-standard specs. They don't know about your bullbar (adds weight), suspension upgrades (can change GCM), or how much you're carrying.
How to find it:
Open your passenger or driver door. Look for a silver or black metal plate riveted to the pillar. This plate overrides everything you read online.
Why Estimates Fail (Real World Expert Tip)
Many owners accidentally tow illegally because they forget Payload.
- • Bullbar & Winch: Adds ~80kg to your front axle (reduces payload).
- • Passengers: 4 adults = ~320kg payload gone.
- • Tow Ball Mass: This comes out of your car's payload, NOT just your towing limit.
Always weigh your rig fully loaded.
This pairing works — now get the required safety gear
Since your Tank 300 is a legal match, ensure you have the required safety gear. Mirrors and a Brake Controller are mandatory in Australia for this weight.
