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.

RECOMMENDED GEAR

This pairing works — now get the required safety gear

Since your Trailblazer is a legal match, ensure you have the required safety gear. Mirrors and a Brake Controller are mandatory in Australia for this weight.

Don't guess with your family's safety. Always take your fully loaded rig to a public weighbridge to get the exact axle weights before your first big trip.
