Caravan review: Prime Edge Caravans Odyssey ATX 21ft

Malcolm Street — 8 January 2024
At its heart, The Odyssey is an epic adventure, and that’s exactly what this 21ft van by Prime Edge promises.

Prime Edge Caravans are a relatively new name in the Australian caravan industry but the owners, Nick and Vlad Suplinovski, are not. Initially beginning by making benchtops for caravans, the brothers moved to building Red Centre Caravans for a third party. Now, they are building the Prime Edge range under their own name.

Except for the TourX, all the Prime Edge vans are built for offroad use. That includes the topline Odyssey ATX 21ft, my review van, organised through the Sunshine Coast dealer Caravan World. When I arrived, the van was hitched up and ready to go, and I was soon on my way to my photography location, Kenilworth Camping, a charming location on the Mary River in Queensland. 

Good looker 

First impressions can mean a lot, and the Odyssey ATX’s gold and black colour scheme certainly catches attention. Under the bodywork is an aluminium frame, which is all hydraulic rivetted. The sides, front and rear are all sandwich panel construction, and the roof is one-piece fibreglass. Mostly out of sight, the floor is also a one-piece, a honeycomb structure. 

There’s a generous amount of external storage built into the Odyssey. In addition to the front tunnel storage and rear offside bin, two checkerplate storage bins are mounted on the drawbar. Fitted with extra drawers and slide-outs, there is space for a barbecue and a generator. In addition to a spare wheel, two jerry cans and a pole carrier are mounted on the rear bumper. 

Prime Edge offers a two-year warranty on factory workmanship, five years on the chassis, structure and water ingress and 12 months on OEM components. 


The ARV-built chassis is a truss design. It looks much like a standard box section design, except that certain sections of the chassis have been removed to save weight, yet without losing any strength. It’s built using Australian steel, galvanised to AS/NZS 2312.2, and then treated to a LINE-X protective coating. The arty design touch is the laser-cut engraving of the Prime Edge name. And to handle the towing load, there’s a Cruisemaster DO45 fitted. 

There’s a fitness-for-purpose look about the sub-chassis area. The water tanks all have alloy checkerplate protection and all the pipework and cabling is fully protected and strapped up well out of the way. Unusually, that includes the grey water piping which is fully enclosed by corrugated PVC tubing. 

ARV’s top-of-the-line airbag suspension is highly impressive with Pedder’s dual shock absorbers. It’s designed to ensure a smooth ride under any load. The suspension system includes a 12V compressor, air tank and tyre inflation kit. The self-levelling system has full and semi-automatic controls. The suspension comes with a five-year warranty. The caravan package includes 16in alloy wheels fitted with Mickey Thompson 265/75R16 tyres. Instead of drum brakes, the wheels are fitted with disc brakes that have an AL-KO iQ7 hydraulic actuator. That’s necessary for power-assisted braking with no time lag.

The tow vehicle

Being built as an offroad caravan, the Odyssey ATX isn’t a lightweight. It has a tare mass of 3050kg and an ATM of 4200kg, which results in a payload of 1150kg. However, that does push the van into Chevrolet Silverado or RAM towing territory. Travellers who are very careful with loading and stay under 3500kg can use something like a LandCruiser or get the Toyota’s towing capacity upgraded. Any of the 3500kg rated utes are not suitable. 

On the road, the Odyssey towed well behind the LandCruiser. It’s a big van, but it was quite stable on the bitumen and the few bush tracks I found during the tow test. I liked the disk brakes; they provided plenty of stopping power when required. 

System utilities

There’s little doubt the power system has been designed for extended off-grid living. Two 300Ah Enerdrive lithium LiFePO4 batteries are the backbone, and they connect to four 210W solar panels via a 40A MPPT solar regulator. 

An Enerdrive ePRO Combi 12/3000-120 is the system’s heart, a combi inverter/charger with a 2600W inverter and 120A charger. Instead of being inside the van, all of the electrical gear is located in an external cabinet on the offside of the van. Apart from anything else, it makes it all easily accessible, particularly for checking and testing. Inside the van, the remaining controls, like the water heater, tank gauges and even the Fusion radio, are in an overhead locker above the lounge. 

There are two 9kg gas cylinders for the cooker, water heater and external gas bayonet — but Prime Edge can fit enough battery capacity for a fully electric van.

In addition to the two 95L freshwater and single 100L grey water tanks, there’s an extra 62L of drinking water to ensure extended travel ability. The hot water comes from a Girard instantaneous heater. 

Welcome aboard 

Just like the outside, the interior creates an excellent first impression. There’s a good feel to the fit-out and finish. The final effect is very understated. All the cabinetry is CNC machine cut and interlocked to ensure a solid finish. The door catches are minimalist in the case of the cupboard and drawers and are hidden for the overhead lockers. I like the rolled bench edge — to me, it is classier and more practical. Touch switches mostly control the downlights and reading lights in a well-appointed lighting system.

Prime Edge has opted for a tried and trusted layout. It’s a rear door entry van with a front island bed, nearside kitchen, offside dining area and a rear full ensuite. The window space is quite generous, offering plenty of blue sky views and natural light, the latter of which is somewhat assisted by the glossy white ceiling.  

Catering and dining

For those who would like to practise their culinary skills, this spacious kitchen has a good benchtop area. There’s plenty of storage space, mostly drawers, cupboards, and overhead lockers. In addition to that, there’s a wire basket pantry adjacent to the 224L compressor fridge on the opposite side. A Hawk four-burner cooktop, grill and oven handles everything from making soup to a Sunday roast. In addition, there’s the usual microwave oven fitted in among the overhead lockers. 

Facing the kitchen bench, the club lounge oozes comfort, especially with the hinged footrests on each end seat. The table isn’t huge but being on a Nuova Mapa mounting, it’s height-adjustable and means the lounge can be used to make up a bed if needed. A reading light, mains power point, and a USB charger hub are on the wall at each end of the lounge. 

Forward area

Up front is a bedroom with plenty of space. The bed is a standard queen (1.83m x 1.53m/6ft 2in x 5ft) pillowtop mattress and there’s a surprising amount of walk-around room, even with the small diagonal cupboards on both sides. As well as the usual overhead lockers, there are shelved cupboards on both sides, each with a pillow cubby. Lifting the bed frame gives easy access to the underbed storage. There isn’t a hatch above the bed; that’s where the CaraFan dust extractor is. However, there are good-sized windows on either side and two Sirocco 12V wall fans. 

Spacious amenities

In keeping with the rest of the van, the rear bathroom has a high level of appointment. The vanity cabinet has a generous number of drawers, cupboard space and overhead lockers. All while leaving enough area for a wash basin and top-loading washing machine. The remaining space is occupied by the offside Thetford cassette toilet and the shower cubicle in the opposite corner. Ventilation is assured by two roof fan hatches and a small window. 

The bottom line 

Prime Edge might be a relatively new name in the caravan manufacturing business but there’s plenty of experience to show in the Odyssey design and layout. The Odyssey has much to offer for a couple who want a van designed for some rough road driving, while still being entirely comfortable with all the conveniences. 

Kenilworth Camping

In the Sunshine Coast Hinterland, there’s a great little camping spot on the Mary River: Kenilworth Camping. It’s actually a working dairy farm and yes you can make friends with the cows, but it’s also a great camping spot which I have used a few times. As it happens it’s also excellent for taking review photos! See to find out more.
