Build date
This service is mainly intended for Ultimate campers manufactured before December 2020. Later campers already use consistent ratings matched to their production specification.
Manufacturer assessment · replacement vehicle plate
Could your Ultimate carry a higher ATM?
Some Ultimate campers manufactured before December 2020 may be eligible for an Aggregate Trailer Mass upgrade. We assess the individual camper, confirm the maximum rating we can support and prepare the manufacturer documentation and replacement vehicle plate.
Assessment service$350 incl. GST
Potential maximum1500kg ATM
Typical processingAllow up to 4 weeks
Check your camper Start with eligibility
Not every camper can be upgraded.
The final rating depends on the camper’s build, chassis, suspension, brakes, wheels, tyres and current condition. A request is an assessment—not an automatic approval.
Suspension and brakes
Earlier Cruisemaster and Sugarglider suspension installations with suitable 10-inch drum brakes may be capable of an increase to a maximum 1500kg ATM and 1400kg GTM.
Condition and evidence
The camper must be roadworthy and the photographed components, ratings and registration details must support the requested change.
The assessment journey
A clear path from camper number to replacement plate.

Add the registration papers and clear camper, plate, wheel, tyre, brake and suspension photographs in the same application.
- 04
Pay the $350 assessment fee
Your evidence is saved securely before Stripe opens. Once payment is confirmed, Ross receives the complete engineering pack.
- 05
Approve the revised details
We send the proposed vehicle-plate details and supporting letter for your review before producing and posting the replacement plate.
- 06
Complete your state process
Fit the new plate only as directed, then complete any inspection and registration update required by your registration authority.
Prepare your evidence
Clear photos prevent delays.
Photograph labels and markings sharply enough to read them. Remove the wheel only when it is safe to do so, or ask a qualified workshop to take the brake-drum photographs.

Tare weight
Tare is not automatically rewritten.
Owner-added accessories can change a camper’s actual empty weight after it leaves the factory. If you want the tare shown on the replacement vehicle plate changed, a current weighbridge certificate is required using the empty-but-ready-for-use condition described above.
Wheels and tyres
Ratings must match the camper.
The replacement plate will normally reflect the tyres currently fitted, provided their size, speed and load ratings—and the wheel rating—are suitable for the assessed camper rating.
