Caravan Review: JB Caravans Scorpion Sting

Caravans sure have changed over the last five years. The revamped JB Caravans Scorpion Sting is a case in point. From the way it is built to the equipment on board, it is a great example of how caravans no longer have to be a ‘stick and tin’ construction with a few features and comforts on board.

Along with the Gator, the Scorpion Sting is JB Caravans’ top-end offroader. Our review model was 23ft, large and luxurious, with an ATM to match the fact that this rig is built for full-time long-haul travels. This van is not for the faint of heart, or the faint of tow vehicle. This van is unashamedly built for the US ute set. Think Dodge Rams and Chevy Silverados. Let’s hitch it up and take it for a test tow…


At Tare, the 23ft JB Scorpion Sting is no lightweight. Our van tipped the scales at 3040kg. You read that right. It has an ATM of 3700kg which, when fully utilised, puts it beyond the reach of the Land Cruisers and Grand Cherokees of the world, and places it in a whole other category of tow vehicle.

scorpion stingThe Scorpion Sting is built atop a 6in chassis, with 6in drawbar and 6in main members. JB has given the steel underbody components a Raptor coating, a durable urethane product that provides a protective barrier against the elements. Not something you see on the average van.

Further, each of the van’s water tanks are properly protected, and that goes for the associated plumbing, too. The storage capacity is 160L across two tanks, plus a separate 65L tank dedicated to drinking water, with a filter included. A 95L grey water tank is also included.

scorpion stingThe Scorpion Sting rides on Cruisemaster ATX coil spring suspension rated to 4.5 tonnes, and as expected, JB has used the 4.5-tonne-rated DO45 offroad coupling. At the rear, mounted to the chassis, you’ll find a couple of rated recovery points so that you can extract from the van from the bog, if necessary.

One of the key features of this van is the option for timber-less construction. While you could have meranti framing, JB now offers a special polyresin composite construction. Instead of timber, the framework is constructed from this special material, which won’t rot or break down over time.

XPS foam – a closed cell structural foam also found in fibreglass sandwich panels – comprises the insulation. This alone is a massive upgrade over the polystyrene many manufacturers still use.

Finally, there’s the one-piece ‘honeycomb’ floor. Complete with an upper and lower skin of woven fibreglass, this flooring system is said to be much stronger than 12mm marine ply, which is also still widely in use, while being 40 per cent lighter. Further, it’s water-resistant, rust and rot-proof.

scorpion stingThis van does well in terms of external storage, too. There’s a large checkerplate storage box on the A-frame complete with a central locker housing two 9kg gas cylinders, and two slide-out trays either side. Meanwhile, this van had a tunnel boot, a nearside locker towards the rear for external access to the space beneath the bunks inside, a roll-out awning, picnic table and much more. 

JB has mounted a spare wheel and two jerry can holders to the rear bumper, but between the van body and the bumper you’ll find a firewood carrier – an unexpected but welcome inclusion. There is also a reversing camera and LED light bar front and rear.


The Scorpion Sting offers another genuine point of difference: the electrical system. It comes with a 5kW EcoFlow power system, which equates to about 416Ah of usable energy, along with a 3600W inverter that’s wired to all 240V powerpoints throughout the van. During our time with the van, we were able to boil the kettle and run the reverse-cycle AC unit without plugging into mains.

At the press of a digital button, you can also isolate the system entirely. Further, you can control everything from a smartphone app.

All of this battery capacity is going to need to some serious solar input. To that end, the Scorpion Sting has four 200W panels on the roof, and of course the battery system can be charged off mains power as well.

The nearside club lounge is a winner, too. Upholstered in faux leather, it is particularly comfortable and roomy enough for five people. I liked that JB had fitted a couple of 240V and USB points in the leg well, which should assist in keeping cables tidy when working from a laptop or similar at the dinette.

The kitchen comes with full cooking facilities, including an oven and microwave. There’s a decent spread of storage space as well, while a Fusion sound system is fitted to the cabinetry above the sink. A series of downlights is fitted to the both the kitchen and dinette bulkheads and you’ll of course find numerous skylights.

Meanwhile, the front bedroom is equipped with Sirocco fans, reading lights and charging points. While the Truma heater is mounted in the storage space under the bed, JB has wisely segmented it off so it won’t be damaged by the bits and pieces you’re bound to store there.

scorpion stingThe fit and finish is up there with the best of them – JB has developed a worthy reputation in this regard and the Scorpion Sting is no different. No sharp or rough edges, or exposed screw heads. It is a well-considered and executed interior.


There’s no doubt, the JB Scorpion Sting is a substantial caravan. While that is reflected in its Tare weight, the van offers so many features and functions, that it’s to be expected. The build quality is serious, too.
