Tiny Home Trailer Buying Guide
Tiny Home Trailer Buying Guide: What to Check Before You Buy
The trailer is the part of a tiny home you stop seeing once the home is built, and it's the part that matters most. It carries the full weight of the home, decides how safely it travels, and in NSW, it's what lets a tiny home be treated as a caravan rather than a building.
This guide covers what to check when buying a tiny home trailer, from size and axles to compliance and cost.
What is a tiny home trailer?
A tiny home trailer is a purpose-built chassis that a tiny home is built on. It's not a box trailer or a car trailer. It has to carry a complete home for years: walls, roof, kitchen, bathroom and everything inside. That means a heavier frame, more axles and a much higher load rating than an everyday trailer.
What size tiny home trailer do I need?
Start with the floor plan, not the trailer. Road rules limit how wide a trailer can be, so most of the extra space in a bigger home comes from length.
Our tiny home trailers come in three lengths:
- 20ft: suits a studio or compact layout. Available as a dual axle, tri axle or with a removable drawbar.
- 30ft: more room for separate living and sleeping areas, on three axles.
- 40ft: our largest trailer, on four axles.
If none of these fit your plan, we can build a custom size.
How many axles does a tiny home trailer need?
More axles spread the weight over more wheels, share the braking load and keep the trailer steadier on the road. As a rule, the longer and heavier the home, the more axles it needs.
The right number depends on what the finished tiny home will weigh, not just its length. A 20ft home with a full kitchen and bathroom can need a tri-axle, where a lighter 20ft fit-out may suit a dual axle. Ask your builder for the expected weight of your build before you choose.
What is ATM and why does it matter?
ATM stands for Aggregate Trailer Mass. It's the most the trailer can weigh when fully loaded, including the trailer itself. For a tiny home trailer, that means the frame plus the finished home and everything you put in it, from furniture to water in the tanks.
Your finished home has to come in under the ATM. If it doesn't, the trailer is overloaded, which is unsafe and can void compliance and insurance. Our 20 ft tri-axle is rated to 4,495 kg ATM with 5,400 kg rated leaf springs.
What compliance should a tiny home trailer have?
In Australia, trailers up to 4.5 tonnes ATM are built to a national code called VSB1, and all trailers must meet the Australian Design Rules (ADRs). A compliant trailer has a Vehicle Identification Number (VIN) and a plate fitted.
Ask to see both before you buy. A trailer without a VIN and compliance plate can't simply be registered later.
It's also worth asking whether the finished home can be complied as a registrable caravan. Ours can when one of our caravan bodies goes on top.
Does the trailer affect council approval in NSW?
Yes. In NSW, a tiny home on a trailer that can be registered is treated as a caravan, not a building. That means it can often go in the backyard of the house you live in without council approval, as long as the people living in it are part of your household.
The home has to stay on its trailer for that to apply. Our council approvals page explains the rules in more detail.
What brakes does a tiny home trailer need?
A loaded tiny home is heavy, so brakes on every wheel matter. Trailers over 2,000 kg ATM need brakes on all wheels and a breakaway system, which stops the trailer if it ever separates from the tow vehicle. Our trailers have electric brakes on every wheel with a breakaway system fitted as standard.
What is a removable drawbar and do I need one?
The drawbar is the front section that connects the trailer to the tow vehicle. A removable drawbar can come off once the home is in place, so there's nothing sticking out from the front of the home to walk around or trip over.
It's optional. We offer it on our 20ft trailer.
Can I tow a tiny home trailer myself?
Probably not with an everyday car. A finished tiny home weighs several tonnes, and most cars and utes aren't rated to tow that much. Check your vehicle's towing capacity before planning to move the home yourself. Most people have their home delivered.
How much does a tiny home trailer cost?
Our tiny home trailers range from $11,000 to $20,900 inc GST.
20ft Dual Axle Trailer - $11,000 (inc GST)
20ft Tri Axle Trailer - $12,200 (inc GST)
20ft Removable Drawbar Trailer - $13,200 (inc GST)
30ft Tri Axle Trailer - $17,600 (inc GST)
40ft Quad Axle Trailer - $20,900 (inc GST)
Custom sizes are quoted on request. Length and the number of axles are the biggest drivers of price.
What should I ask before buying a tiny home trailer?
- Weight: what is the ATM, and what will my finished home weigh?
- Compliance: is it built to VSB1 or the ADRs, with a VIN and compliance plate fitted?
- Registration: can the finished home be complied as a registrable caravan?
- Running gear: how many axles, and what are the springs and tyres rated to?
- Brakes: are there brakes on every wheel and a breakaway system?
- Build: where is it built, and can I see one in person?
- Delivery: is delivery included in the price?
