Car-Transporter.pngWelcome to Trailersauce.co.nz

Welcome to Trailersauce, your guide for all you need to know about building a new trailer, buying a trailer or maintaining your existing trailer.

Trailersauce has been set up to allow both the handyman and engineer to have access to free trailer designs and information, as well as providing general trailer information for anyone who wishes to learn more about their existing trailer, how to maintain it and how to operate it safely.

I hope you find using this site, free drawings and instructions easy to follow, and any potential trailer build rewarding.15ft_Boat_Trailer.png

I have been engineering for over 30 years and have had many years designing and building trailers professionally.

As time goes on, I will be adding more trailer plans and information, so check back often.

The free trailer plans within this website are easy to understand and are set in a way that will take you step by step through the build with both instructions and easy to read drawings.

Flatdeck-Trailer-2-trans-w355-h180.pngAll the trailer designs on this website comply with New Zealand Transport Agency requirements and are Australian ADR VSB1 compliant.

These plans are infinitely adaptable to whatever end requirement you have and as long as the basic rules and your local transport laws are adhered to, you can customize each design as you wish.

Tow_Dolly__car_on_3-w355-h180.pngYou will not find fancy, hard to read CAD (computer aided design) drawings or overly technical drawings on this website, as many of these drawings get bogged down in the details and can be for many (including engineers), difficult to read and visualize. Here you will find easy to read sketches and descriptions to see what things should look like and step by step instructions on how they go together in the correct order.

Some of the free-plans now have a $5 downloadable version which are print friendly and ad free. If you are serious about building a trailer, this is the way to go!

If you require a quotation on trailer parts and components within NZ, please feel free to contact us here with your requirements, and we will be happy to provide you with competitive pricing.

We would love to see your photos of your trailer build and finished product. Also check us out at Facebook!

Good Luck and happy trailering!



Getting Started

Should I build or buy a trailer?

TWelder_2-w187-h274.jpghere is something very rewarding about building your own trailer and if you have the time, equipment and the space to embark on this task, then this is an easy question to answer. Once you have your own trailer, you will find uses for it that you would never have imagined!

Building your own trailer can be a good evening project done over a couple of months, or if you have a well set up workshop and the skills to accomplish it, you could have a fully functioning trailer completed in a couple of weekends.

Just remember that building a trailer is not necessarily the cheapest option and can, depending on the options you put into your trailer, be more expensive than buying a new trailer from your local manufacturer - BUT - there is almost nothing in the world better than driving down the road towing a trailer that you have crafted using your own hands and skills!

It gives a great feeling of satisfaction to have built a trailer that is uniquely yours and something that you can be proud of.
