Proven By The People
Who Tour With Them
Your Renegade 12 is built by the same team, in the same workshop, and backed by the same after-sales service as every Rhinomax on the road. There are now over 1,000 Rhinomax owners touring Australia. Here’s what they say about how they’re looked after.
“After spending 11 months travelling half of Australia, Max — our Defender — needed a good service… I absolutely love that the team care so much for our van. Nothing is too much trouble, and I’m pretty damn fussy. The after-sales service is second to none.”
“We’re NSW based, so we organised it all over the phone and online… We recently travelled to Queensland to pick up our Defender hybrid, and the quality build is outstanding — right down to the handover. The van towed like a dream on the 1,077km trip home.”
“From the moment we made our first phone call to the day we picked our Defender up, the service and patience was second to none… You hear a lot of complaints about after-sales service from well-known brands, but with Rhinomax it was exceptional.”

Good To Know
Lost Trak 18.5 Questions, Answered
The things serious buyers ask before ordering — straight answers, no run-around.
What tow vehicle do I need for a Lost Trak 18.5?
This is the heaviest model in the Rhinomax range and it needs a serious tow vehicle. With a 3,500kg ATM you need a 4WD rated to tow the full 3,500kg — a 200/300 Series LandCruiser, Patrol, Ram, F-150 or similar. Many popular dual-cab utes are rated to 3,500kg on paper but run out of GCM long before you reach it.
The 240kg ball weight matters just as much. A towbar or hitch rated to 200kg or less is not enough, and plenty of factory bars are. Check your vehicle’s braked towing capacity, ball load limit, GVM and GCM together before ordering — our team will go through your exact setup with you, and we would rather have that conversation now than after your build starts.
Is it still off-road capable at 18.5ft?
Yes — it runs the same hot-dip galvanised Performance Chassis and Cruisemaster off-road suspension philosophy as the rest of the range, here in a dual-axle configuration with Cruisemaster XT 3,500kg airbags and a DO35 off-road coupling. Adjustable ride height and load-levelling are standard.
Be realistic about what changes with size, though. At 7.3m overall it needs more room to turn, more room to reverse, and more thought about tight tracks and overhanging scrub than a 12ft Renegade does. It is built to go well beyond sealed roads; it is not built to follow a hardcore single-vehicle track. If your touring is remote but on formed roads and station tracks, this is the flagship for it.
How long does a build take?
Please contact our sales team for current lead and build times on the Lost Trak 18.5. Every one is hand-built to order at our Sunshine Coast workshop, and your specialist keeps you updated throughout the build.
What warranty comes with a Lost Trak 18.5?
Every Lost Trak 18.5 is covered by our 5-year structural warranty, with appliances covered by their manufacturers’ warranties. Rhinomax facilitates warranty claims with third-party suppliers on your behalf, so after handover you keep dealing directly with the team that built your caravan — no call centres, no service tickets.
Is finance available?
Rhinomax doesn’t offer finance options in house, however we can recommend a number of reputable finance companies if needed.
I’m interstate — can I still buy one?
Absolutely — plenty of owners spec and order remotely. You’ll work with a dedicated specialist over phone and video for every decision, and you can view the Lost Trak 18.5 at our Sunshine Coast HQ or through our NSW dealer, Off Grid Outfitters, in Smeaton Grange and Newcastle.
Collect from our Queensland workshop with full handover instruction, or ask us about delivery options.
Do I need an appointment to view one?
Yes — viewings are by appointment so a specialist is dedicated to you for the entire visit, whether that’s at our Queensland HQ, our NSW dealer, or a private virtual walkthrough. Booking online takes under a minute.
