We have been proudly providing quality trailer plans since 2008, starting with a single box trailer plan and regularly adding to a range of practical designs. Our plans are specifically designed to meet Australian regulations and have been used extensively by trailer builders across Australia and  from many other parts of the world.

We’re not just about trailer drawings. We provide compliant plans that will get your project going, saving you time and money during your build

We stay abreast with trends in trailer manufacture – new materials, regulations, products and equipment – and where required incorporate updates or changes into our plans. In 2010, due to growing demand, we created a company, Okajaro Pty Ltd, which trades as TrailerPlans.com.au and continues to provide great products and the same high level of support to our trailer building community.

Key to our success is a strong technical background and formal engineering qualifications. Our plans are designed and detailed by a registered professional engineer with extensive automotive, manufacturing and trailer industry experience.

Our work in the trailer industry includes extensive design and development, through to testing everything from independent suspension systems, couplings, off-road trailers and advanced trailer chassis. We have advised and assisted numerous caravan and trailer manufacturers with development their products (manufactured locally and abroad) or solve performance and handling issues.

 

We are also TMR Approved Engineers, authorised to carry out engineering inspections and approve modifications to local and imported vehicles and trailers.
