WHAT ARE YOU BUILDING FOR?
A trailer? A truck body? A water truck? Or a complete working solution?
At AJ Stock, the starting point is always the work.
Because every application has different demands — from construction and infrastructure to mining, government and remote operations. The right transport solution starts by understanding the job, the environment and what the vehicle needs to deliver.

WATER ISN’T THE JOB. THE WORK AROUND IT IS. 💧🚛
From road construction and dust suppression to site management, parks, landscaping and emergency water supply, water plays a critical role across Australian working environments.
That’s why the right water truck needs to be more than a tank on a chassis.
It needs to be ready for the work, the environment and the demands of the job.
One truck. Multiple working environments.
AJ Stock water trucks are engineered around real-world applications — helping Australian operators keep sites moving and work progressing.

LOAD IN. TIP OUT. KEEP MOVING.
A tipper body isn’t just about carrying material — it’s about keeping the work cycle moving.
From construction materials and aggregate to earthmoving applications, every load needs to be handled efficiently through repeated loading, transport and tipping cycles.
At AJ Stock, our tipper bodies are engineered around the realities of Australian work — practical, purpose-built and ready for the job ahead.

SIMPLE CONFIGURATION. SERIOUS WORK.
A flat top semi trailer provides a practical platform for operators who need straightforward load-carrying capability across demanding transport applications.
At AJ Stock, trailer configuration starts with the requirements of the job — from the way loads are handled to the conditions they operate in.

A trailer should do more than carry a load — it should suit the way the load needs to be carried.
AJ Stock Drop Deck Semi Trailers are designed around the requirements of the job, with configuration considered alongside load height, ground clearance, access, payload requirements and site conditions.

🚛 The job doesn’t end when the load is delivered.
A tipper body is part of the operator’s daily workflow — from checking and accessing the body to loading, tipping, cleaning and getting back to work.
That’s why good design needs to consider more than payload and structural strength.
Access is part of productivity.
At AJ Stock, we build truck bodies around the practical demands of Australian work environments — with a focus on usability, durability and getting the job done.
