Blue Tongue Overland XR vs Isuzu MU-X

What's the difference?

The Overland XR Series 2 isn't quite the perfect camper, there's a few little things in the set-up that preclude it from that. Still, at the price and with the features it gets as standard, it's a really good value trailer. It's comfortable, it'll handle off-road trips with ease, and it the kitchen is really quite good.

The MU-X has always had plenty of appeal as a daily driver – dependable, not dynamic – and it’s a proven 4WD wagon.

Some people don't like the noisy, sluggish engine, but I don't mind it because it delivers off-road.

There was already a lot to like about the seven-seater wagon in terms of its off-road capability, driver-assist tech, standard features, and simple all-round driveability, and the X-Terrain – which encompasses all of that AND adds some polish to the mix – is an impressive top-shelf addition to the MU-X line-up. Even if it's so pricey...

As the lid becomes the floor, it's quite open inside the camper, with plenty of room to move around and space to do everyday things standing up, like get dressed, which is often more difficult in a forward fold, as there's not a lot of standing room inside them. There's also no stairs to climb getting in or out, as the hard floor is almost at ground level.

The tent seems quite well made. It's a 450gsm waterproof canvas with a tropical roof, windows all around the bed and three doors, one each side of the hard floor. Almost the whole passenger side can be rolled away, too, creating a giant opening into the camper, which offers a pretty good outlook on hot summer days at campsites by the beach.

There's no shortage of extra canvas, either. There are two awnings (although only one you'll use often, an ensuite tent and an optional kids room. The best of the awnings is the quick version, which is simply a rectangle of canvas that shelters the kitchen and only needs two poles to hold it up. A more complete awning, which also comes with walls and a floor, goes up reasonably easily, but it'd only be used if you were settling in for a week or more, I reckon, and then only if the weather was questionable. Its pitch has been improved over the Series 1, which had a flatter roofline and was more susceptible to pooling water. The ensuite room is gigantic – about the size of an actual small bathroom.

One of the biggest reasons to get a rear-fold over a forward-fold is the internal access to storage. As the rear-fold's is all under the bed, the four steel drawers make it easy to get to. Two of them are even accessible when the camper is shut, which just isn't the case in a forward-folding camper. A large, wide step makes climbing up into the bed easy, too. It has an innerspring mattress which is firm but comfortable and plenty big enough to spread out on if you are sharing it.

The Overland XR Series 1 was very well equipped electrically, maybe too well equipped. It was fitted with three 100ah batteries, which is not only a lot of extra weight, but that much battery takes ages to charge – if they were all flat, a day's driving probably wouldn't do it, especially if the car also had a second it needed to attend to. The Series 2 has dropped back to two batteries, which is far better suited to the camper and should easily be maintained by one of the optional 144W solar panel blankets. It can also be fitted with Redarc's Redvision, offering phone connectivity to the camper's electronics so you can not only monitor everything, but turn things on or off remotely.

The other side of the camper's forward storage is large enough to fit a generator or any other bulky camping appliance. As it can be accessed when the camper's open or closed, it's perfect for all manner of gear. A smaller box facing forwards is great for hoses and recovery gear or even a couple of jerry cans. Beware of loading this area up with too much really heavy gear, though, as the ball-weight's already on the heavy side. Fortunately, the camper has a flip-over luggage rack, which is ideal for heavier or bulkier items. Underneath, it can carry 155-litres of water in two tanks.

The interior has a pleasant, familiar and practical feel about it and this is an easy space in which to swiftly become comfortable. 

Controls are easy to locate and operate and charging options are numerous – a mix of USB-A, USB-C and 12V up front, and USB-A for the second row.

Storage places include recesses for your everyday carry gear, a suitably deep centre console, as well as dual cupholders up front, cupholders in the rear fold-down centre armrest and bottle holders in the doors.

There are cupholders either side of the third row in the MU-X for passengers riding back there.

The MU-X has physical-button options to activate some functions (including to switch on the audio system, to adjust volume, access sat nav etc).

Seats are adequately comfortable and supportive through all three rows – yes, even the third row is roomy enough to prevent whining from whoever is stuck back there.

The cargo area is 311 litres with all three rows in use, 1119L with the third row flat and 2138L with the second and third rows folded.

The rear cargo area has a cargo cover, tie-down points, a 12V power outlet, a storage space under the rear cargo area floor and a space for tools inside the driver’s side rear cargo wall.

The Overland XR is very stable under tow, which has a lot to do with its ball-weight. Weight to the front of a trailer improves trailer stability (although reduces braking and steering efficiency), so there needs to be a compromise. At 180kg, that's actually a reduction on Series 1, and although that's quite heavy for a camper trailer, is on par with other modern rear-folds, like the Kimberley Kamper.

Well and truly off-road ready, the XR has independent coil-spring suspension and dual shock absorbers, standard, as well as an AL-KO 360° ball hitch, so obscure angles on a rough track won't cause any trouble.

The camper is quite tall, thanks to the spacing of the suspension arms, so clearance will rarely be an issue – when level, the ride height suits a lifted four-wheel drive.

Alloy wheels and 265/75 R16 all terrain tyres fit the bill nicely, and as they're a six-stud LandCruiser pattern, they, and the two tonne bearings, are easy to replace anywhere you find yourself.

In previous tests, the MU-X has been fine on road and more than adequate on gravel, dirt tracks, and during low-range 4WDing. But it’s been a jarring, skippy ride on irregular surfaces rather than as composed as it could – and should – have been. The culprit? Firm suspension, over-inflated tyres, too-tight trousers, who knows?

The good news is it seems like Isuzu has ironed out any issues in the suspension, minor or otherwise, because the MU-X is now is a lot better in terms of ride and handling than ever before. 

Off-road, the MU-X has always been a proven combination of its 3.0-litre, four-cylinder turbo-diesel engine, clever six-speed automatic transmission, and an off-road traction control system that's been increasingly well recalibrated through a number of generations. 

The engine is tractable and gruff, it has plenty of grunt and, as long as you're not driving like a complete hoon, you can usually get through most obstacles without a lot of fuss.

It's this mix of mechanicals and driver-assist tech that make the MU-X such an effective 4WD package. And there are a number of reasons for that. 

For one, that engine delivers plenty of torque down low and in the mid-range torque and that's crucial for four-wheel driving. 

And another thing, Rough Terrain Mode – like a beefed-up and fine-tuned off-road traction control – proves very effective because it punches torque to the wheel with the most traction – while wheel spin on tyres that aren't touching dirt is minimised – and that way it keeps the vehicle moving through obstacles with safe and controlled momentum. 

As I’ve noted before though, Rough Terrain Mode is not a magic all-conquering solution, but it is another handy addition to the MU-X’s off-road toolbox.

And the MU-X also has a rear diff lock to back you up – and that's another valuable component. 

The MU-X has approach, departure and ramp-over angles of 29.2, 26.4 and 23.1 respectively.

A listed 235mm of ground clearance is about standard for this kind of wagon but, as I’ve said before, it seems vulnerable in the underbody, side steps and its plastic mud guards. So the underbody may touch dirt, depending on how challenging the terrain is. 

Wading depth is listed as 800mm.

But, as always, with focused driving, you’ll have lots of fun and you'll minimise any superficial damage or scuff marks to the MU-X.

The MU-X has plenty of potential as a touring platform, but, if you’re planning to do any off-roading beyond well-maintained tracks, then get rid of its road-biased tyres and replace them with all-terrain tyres.

The showroom-standard tyres on this MU-X – 265/50R20 Bridgestone Dueler HTs – are okay, but not really up to scratch if tough 4WDing is what you’re keen to do. I’d prefer an 18-inch wheel and tyre package with decent all-terrains.

The MU-X has a full-sized underslung spare and in terms of packability, the MU-X X-Terrain has a listed payload of 605kg, GVM is 2800kg and GCM is 5900kg.

If you are considering using your MUX as a tow vehicle, it's handy to know that it can legally tow 750kg (unbraked) and 3500kg (braked), which is the standard for large four-wheel-drive wagons. 

Be aware though that, as with any other vehicles, once you're towing anywhere near the maximum weight, your payload is greatly reduced.
