Box trailer vs enclosed trailer is one of the most common decisions Australian buyers need to make when choosing a trailer. Whether you’re a tradie, weekend adventurer, small-business owner, or homeowner, understanding the difference between a box trailer and an enclosed trailer is essential for safe and cost-effective towing.
Choosing the right trailer is crucial whether you’re a tradie, weekend adventurer, small-business owner, or homeowner tackling regular transport jobs. Two of the most popular options on the Australian market are box trailers and enclosed trailers. While both serve similar purposes, they offer very different benefits depending on what you need to tow.
In this guide, we compare box vs enclosed trailers, explain the pros and cons of each, outline typical use cases, and help you decide which trailer delivers the best long-term value.
What Is a Box Trailer?
A box trailer, also known as an open trailer, is a flat-bed trailer with raised sides. It is widely used in Australia due to its versatility and ease of loading.
Common Features of Box Trailers
- Open-top design
- Steel or galvanised body

- Sizes range from 6×4, 7×5, 8×5, 10×5 and more
- Suitable for most small to medium transport jobs
Benefits of Box Trailers

- More affordable than enclosed trailers
- Ideal for bulky or irregular items
- Easier to clean and maintain
- Great for domestic and commercial use
What Is an Enclosed Trailer?
An enclosed trailer, sometimes called a cargo trailer or canopy trailer, comes with solid walls and a roof. It provides complete protection from weather and theft.
Common Features of Enclosed Trailers
- Fully enclosed body
- Lockable doors

Benefits of Enclosed Trailers
- Maximum security for tools, equipment, and valuable goods

GVM, Brakes, and Towing Requirements
Before choosing a trailer, consider:
- GVM (Gross Vehicle Mass)
- Braked vs unbraked axles
- Your vehicle’s towing capacity
- Length and width regulations under NSW road rules
For example:
- Trailers under 750 kg ATM can be unbraked
- Heavier enclosed trailers usually require braked axles
- Your vehicle’s towing limit must exceed the trailer’s ATM rating

FAQ: Box Trailers vs Enclosed Trailers in Australia
1. Which trailer is easier to tow?
Box trailers are generally lighter and easier to tow, especially for beginners.
2. Are enclosed trailers worth the higher price?
Yes—if you need weather protection, security, or additional storage features.
3. Do I need electric brakes?
For trailers over 750 kg ATM, NSW regulations typically require braking systems. Many enclosed trailers exceed this threshold.
4. Which trailer lasts longer?
Both last many years, but galvanised trailers resist rust better and are ideal for coastal regions.
Final Recommendation
If your priority is versatility and affordability, choose a box trailer.
If you need maximum protection, security, and organisation, an enclosed trailer will serve you better long-term.
