What's the difference?
Ford’s legendary F-Series has been America’s best-selling truck for more than four decades. A major factor in that success is the Super Duty range (F-250/F-350/F-450), which reports for duty when loggers, landscapers, miners, oil-field workers and anyone else with seriously heavy on- and off-road load-hauling requirements needs more than the entry level F-150 can deliver.
Not surprisingly, such extreme-duty towing is also required in Australia, particularly by tradies with heavy equipment, and/or for recreational and sporting pursuits that involve multi-axle caravans, horse floats, boat trailers and the like. Some of these large trailers feature a goose-neck design which requires a prime mover-style turntable coupling mounted in the cargo tub.
There are a number of small volume importers which cater for these specialised requirements, including Harrison F Trucks at Melton in Melbourne’s outer west. Harrison provides ADR-approved right-hand drive conversion, local certification and sales/after-sales service for these American giants, one of which we recently sampled for a few days to see what life is like in the world of the Super Duty.
People with camper-trailers are increasingly looking to push their travel boundaries and so they head off the bitumen, onto dirt roads and go bush.
But on-road camper-trailers are not suited to cope with the extra stresses that dirt-road or gravel-track driving bring, which is why campers better equipped for light-duty bush driving, such as Jayco’s Outback versions of its models, are finding favor with buyers.
We took an Eagle Outback into the bush to check it out.

If you’ve got something really heavy to tow and you have the budget to do it in grand style and with minimal effort, then a Super Duty could be just what you’re looking for. Its gargantuan proportions make it impractical for daily driving in Australian city and suburban traffic, but as a heavy-duty tow vehicle, particularly for long-haul open highway work, you’ll feel like king of the road.

The Jayco Eagle Outback, for me, is an example of a camper-trailer getting closer to what I reckon a truly off-road-capable Jayco camper will be like.
There's nothing in Jayco's current line-up that offers comfort and full functionality and is also capable of tackling decent off-roading, so we're looking forward to testing Jayco's first line-up of dedicated off-road campers, including the JTrak Outback and Outback X.
Our F-350 test vehicle with its F-250 downgrade results in a 700kg decrease in both payload and tow ratings. In other words, based on Harrison’s figures, in full F-350 specification it has a 1700kg payload capacity and 9700kg GCM, which means it can legally tow up to 4510kg of braked trailer with a full payload or up to 6210kg without. In our F-250 form it offers a 1000kg payload with 9000kg GCM, and can legally tow up to 3810kg of braked trailer with a full payload, or 4810kg without.
The huge cargo tub has a load floor length of 2080mm and width of 1700mm, with 1283mm between the wheel arches allowing ample room for a standard 1160mm-square Aussie pallet. There’s a total of eight tie-down points, overhead and internal lighting plus key fob operation of the tailgate, which houses a handy fold-out step and grab handle for easy cargo tub access.
The sumptuous cabin has plenty of storage options, including a single glovebox, and a bottle holder and two storage bins in each front door. The centre console has an open storage cubby at the front, another open storage bin and two bottle holders in the centre, a cavernous box behind that with a padded lid which doubles as a comfortable armrest, and two more bottle/cup holders at the back.
Those in the rear seat also get a fold-down centre armrest with two pop-out cup holders and each rear door has a bottle holder and two storage bins. There are also flexible storage pockets on the rear of both front seats and the 60/40-split rear seat base cushions swing up through 90 degrees and lock into position, revealing a huge full-width storage area underneath.
These Jayco camper-trailers have a familiar touring-friendly floor-plan – check out the accompanying photos for proof of that – and most adhere to a similar approach to interior functionality – neat and simple – and that’s well suited to those who venture off the blacktop and hit the dirt.
Interior height is 2070mm, standard for campers of this type, so there’s plenty of stretch space for those of us not gifted with the vertical inches of Collingwood’s Mason Cox. Bench height, also standard for a camper-trailer, remains just lower than an average bloke’s hip so stooping to work in the kitchen is still an issue, but that’s part and parcel of the lifestyle, so stop whinging and get used to it.
Looking from the door, to the left is the front bed and club lounge; along the wall is the kitchen area (replete with four-burner stove, Dometic 95-litre fridge*, storage drawers and pantry); and to the right is the rear bed and dinette area. (* Outback models get the 95-litre fridge; Touring models get the 90-litre fridge.)
Overhead interior lighting includes LEDs for the main area and reading lights for the beds; there’s a fan for the beds.
There are also power points and USB port.
You sit up nice and high in very comfortable seats, with a commanding view of surrounding traffic and the road ahead. We quickly adapted to the width and height of the Super Duty, but the major issue in city and suburban driving was its oil-tanker length, which required later turn-in on tight corners to provide kerbside clearance. We also needed to check that there was ample reversing room when choosing a space in a parking lot, to ensure we didn’t get wedged when trying to leave.
With the big turbo diesel V8’s 1267Nm of torque being tapped at only 1800rpm, it provides spirited getaways from traffic lights, and easily keeps up with normal city and suburban traffic flow with your big toe barely touching the accelerator pedal.
The ride quality without a load is quite good on smooth surfaces, with its massive 3.5 tonne kerb weight feeling like the tyres are leaving indents in the bitumen. However, over rougher roads and larger obstacles like speeds humps, it starts to bounce around more and can feel quite ponderous at times. However, this is to be expected in an empty vehicle with such high payload and tow ratings.
The steering is surprisingly direct and firm in feel. It’s also quite linear in turning weight regardless of road speed, without the more noticeable changes evident in its little brother Ranger, which is very light at parking speeds but gets noticeably firmer as speeds increase.
Braking is reasonably responsive but like other giant US pick-ups we’ve tested, you have to get them quite hot to make them really bite. That’s because their pad compounds tend to be on the hard side, given they have to cope with the high temperatures generated by heavy-duty towing.
The engine exhaust brake is surprisingly quiet and very effective at slowing the vehicle, aided by more aggressive downshifts in the six-speed auto.
This single-axle camper – at 5060mm long (including drawbar), 1910mm high, 2240mm wide, and with a 1270kg tare weight – towed smoothly behind the Mitsubishi Pajero Sport we used on this review.
It sat snug and steady on the towball (with a 150kg download) during open-road driving, as well as during short sections of slightly bumpy gravel track and undulating dirt road.
The Eagle Outback has a hot dip galvanised Endurance Chassis riding on Jayco’s own JTech coil-spring suspension set-up.
Please note: Jayco’s Outback models are designed and engineered for, at worst, dirt roads and gravel roads, not 4WD tracks. Do not think that because these campers have been branded ‘Outback’ that they are actually able to tackle hard-core off-roading.
