Guide hubs
Every article on Custom Trailers sits in one of six desks. Start here if you are specifying a build, arguing with a plate, or trying to keep last summer's trailer on the road.
Before you sign
Buying guides
Most expensive trailer mistakes happen on the quote, not on the highway. This desk covers how to write a brief a builder can price, how to read an Australian plate, and which questions separate a workshop from a brochure.
Steel, finish, wire
Builds and materials
A custom trailer is a set of materials pretending to be a vehicle. These pieces walk through steel versus aluminium, hot-dip galvanising versus powder coat, drawbar geometry, floors that drain, and looms that still work after a Cape York wet.
The right shape
Trailer types
A 7x5 is not a specification. Each trailer type has a duty cycle, a plate problem and a finish that either lasts or rusts. Use this hub to match the shape to the week you actually have.
- Cage and landscaping trailers
- Plant and machinery trailers for Australian sites
- Camper trailers: hard-floor versus soft-floor
- Horse floats and livestock trailers in Australia
- Boat trailers: rollers, bunks and Australian ramp launches
- Car trailers and enclosed car transporters
- Custom box trailers for Australian tradies
ADR and registration
Regulations
Australian Design Rules and state agencies decide whether a custom trailer can be plated and used. We translate ADR 38, ADR 13, ADR 62 and the registration counters without pretending this is legal advice.
On the bitumen
Towing and safety
The trailer only exists as a combination. These guides cover tow ratings, GCM, 50 mm balls, pintle and gooseneck couplings, weight-distribution hitches and the sway that shows up at 95 km/h on the Hume.
Keep it on the road
Maintenance
A trailer that is never serviced becomes a story at the boat ramp. This hub is the yearly schedule, the bearing job, and the rust habits that decide whether a galvanised chassis lasts twelve years or four.
