The job can change. Your truck body should be able to change with it.
When a customer needed side access for pallet loading, AJ Stock adapted the build to suit the requirement — turning a challenge into a practical, purpose-built solution.
That’s the value of a true custom truck fit-out: not just building a body, but engineering it around how you actually work.

Before the load hits the deck, the planning starts.
A flat top semi-trailer needs to work with more than just the freight. Load type, positioning, securement, loading method and day-to-day operation all matter.
From steel and machinery to containers and general freight, the right setup starts by understanding what the job actually demands.
At AJ Stock, we believe the trailer should support the operation — not limit it.

🚛 GET THE COMBINATION RIGHT.
A dog trailer isn’t simply an extra piece of equipment — it needs to work as part of the complete transport combination.
From the truck and trailer to the load and application, every part needs to work together for the job ahead.

🚛 Your body has to fit the truck.
A truck body isn't an isolated component. Mounting, chassis configuration, wheelbase, clearances and the overall vehicle setup all need to work together.
Getting the fit right from the beginning can help create a more practical, integrated transport solution for the job.
BODY + CHASSIS + APPLICATION = THE RIGHT FIT

A truck body shouldn’t just be built to work — it should be designed to keep working.
From accessibility and practical design to robust components, reduced complexity and long-term thinking, good body design can make everyday operation and maintenance more straightforward.
At AJ Stock, we believe the best design starts with understanding how the truck will actually be used.
Design for the work. Design for the years ahead.
