Thread: DESIGN AN OUTBACK, REMOTE AREA, EXPEDITION VEHICLE

Dare I say it, but my TD42 + T powered GU Patrol with 135 litres of factory fuel capacity and homemade storage system is for me the right combination of reliability, strength, capability, simplicity, power and economy for family outback touring. It has well and truly proven itself in this regard. With 280k on the clock, the body is now sporting a fair few cracks thanks to countless corrugations, but mechanically it is holding up well.

Having said that, the Iveco 4 x4 looks even better but is out of my budget.

Dont get me wrong, I (mostly) love my Land Rovers and am currently building up a Perentie for for the kind of 'touring' Dave S was talking about earlier, but credit is due where credit is due.....

The 4.2l 6.07 MWM turbo diesel engine out of the F250's delivered to Aus (more power, quieter, smoother and 60kg lighter than a 4bd1t - and just as fuel efficient) with a ZF5 and NP271 transfer, all put in a 2005+ US F250 (coil sprung front), with one of these on the back:
XPCamper | V1 - Full Size - XPCamper

Turtle expeditions have been going round the globe in a similar setup since the 80's.

I'd choose my current vehicle (2012 F250), but the prospect of getting water in the fuel, and having a $16,000 fuel system failure in the middle of no-where doesn't seem like fun.

The swag etc. gets old when you are dealing with lots of bugs, or "inquisitive" locals. I've ridden most of the planet from the back of a dirt bike - fun, but if you are doing it year in, year out, you get to appreciate some comfort.

BigF350 - that XP/V1 camper unit looks amazing! I see its advertised pricing is:

Camper with truck tray starting at $79,825 installed.

That 4.2 diesel is a 6 cylinder version of the HS28. Serge might have something to say about that. Particularly parts supply and cost.

You won't get the same fuel economy as a 4BD1T It's 6 cylinder so more internal friction and more heat loss from the cylinders. Both mean lower efficiency.
It has 132kw/510Nm in best form. You can beat that with a 4BD1T before you install an intercooler.
Parts supply would be a problem. Just trying to find info on those engines is a task:

But the camper looks excellent.

Not if you speak Spanish or Portugese
Parts are substantially cheaper than OEM Isuzu in my experience

I can't speak to thermal efficiency, and don't question that on paper its not as efficient as a 4bd1t, but it will move a 3tonne F250 along at around 11l/100km. I can't imagine a 4bd1t would be appreciably better in such an application.


I'm sure you can beat the power listed with a 4bd1t, but not from the factory. And if you start going in that direction... well...

A stock 4BD1T can go to around 180hp just by turning screws. So yeah, completely factory.
Swap the turbo, install an intercooler, turn the screws further and you're around 800Nm/200kw. Still no internal changes.

Randy (Carcrafter) in the US had a modified injection pump and compound turbos on his 4BD1TT. It was a conservative 500kw. He was running 7x as much fuel as stock, but burnt clean. He put the 100psi gauge off the end and that killed the auto gearbox.
Sadly that vehicle was lost in parts in a divorce. The engine was sold off in a jeep with single turbo dyno'd at 350rwhp.

The one in that video is a seriously bad tune. It's just dumping fuel and has nothing down low.

The trouble with big 4 pot diesels is that they tend to shake whatever they are in to pieces, and their torque is very course.. 6 pots are smoother, and more gearbox friendly.. If they're direct injection they're also pretty good on fuel. A big lazy 6 hardly breaking a sweat is a better option than a 4 working its nuts off IMO... 8500kms now covered in the Cummins powered 101, and never more than 12lt/100km.

If you were on your own i would start with a suzuki siera 1.3 ltr hardtop no electronics much,good fuel.,get the suspension modified a little so it is not so harsh,some good seats,possibly airconditioned,
