BRILLIANT. I am down as well with my auto 2004 auto with duallys .
I love how we all have different reasons for doing what we do. It is refreshing to hear someone who actually thought about it!
SWEET on the dimensions MOG. Are the dim shown to the outside of the wheels front and back or centerline. Just want to make sure. Thanks!
It would be centreline. The difference you will see is that to stabilize the vehicle under cornering loads they will try to put the effective wheel track relatively similar front and rear. What this means is that the inside rear runs narrower to the front, and the outside rear runs wider. If you can conceptualize how soft sand folds in behind tyres, you will see how this is a bad thing, as now you have 6 tyre faces effectively trying to climb soft sand as opposed to 2, if you run singles in a similar wheel track. 70 series Land Cruisers encounter a similar problem here in sand, because even though they have singles, the rear wheel track is 4in narrower than the front.
The fuso setup is different to how "Dually pickups" in the US run, where the inside tyre of the rear runs very similar track to the front, and the outside rear runs significantly wider. The cab chassis versions of the Ram/F350/F450/F550 run narrower chassis/rear axles and run similar wheel track setups to the Fuso.

Here it is to scale (quick freehand). You can see the inside wheel is cutting new ground for the most part. This assumes a 2 inch gap between tires. If you are turning, the rears driving in the front track is moot (srw or dual). However, MOG is correct that even when turning, 6 wheels pushing sand is a greater resistance to 4 wheels pushing sand. If going straight one could say that 2 wheels pushing sand is greater than an equivalent 4 wheels pushing sand given some of the overlap. So there is a clear advantage to the singles here.

Julian said there is "data" and there is "marketing" ......do you mind if I use your drawing for marketing??? Hahaha. Well done mate.
There are some great thoughts starting to come out in this thread.
Kind regards John.

Yup, for the set of Singles I will even sign it.

All seriousness aside, you could sponsor the Sandbox Experiment...:smiley_drive:

Hey. We are planning travelling to Oregon in September. I could run in the sand then. Does anyone have a winch I could borrow in case I get stuck? ;-)LOL
and of course the other reason many people in Australia derate there Canter is because they can be driven on a normal car license, any vehicle up to 4500kg in Australia can be driven with a car license, over this you must have a truck license, I have not checked but I'm sure the registration would also be a lot cheaper, so there are many reasons for derating, i hate to think how many people are driving around in heavy motorhomes only with a car license.

My license lets me drive pretty much anything with wheels, so I have never really thought about this too much.
I wonder how diligent the police officers are if you get pulled over. Do they question you on the GVM of the vehicle and compare that to your license? Does anybody know?

not only does less than 4500kg allow driving on a car licence it also allows vehicle registration renewal without annual inspection, in Queensland - which is really useful if its been packed in a container and shipped overseas for 3 years! 
Very much at odds with the international drivers permit which has a boundary at 3500kg - so a medium rigid (don't you just like the terms) licence with lots of stamps in the idp keeps overseas traffic police at bay.
The single wheels had the unforeseen side effect of attracting considerably lower road tolls in Myanmar where there are so many categories, based on number of wheels, that every toll barrier is a fresh negotiation. Windows in the box were the key to crossing the long bridges in UK. Nothing helped with the long Danish bridges.
On a more serious note .... ploughing through several continuous km of soft sand in second gear, marked "bad dunes" on Olaf's map of Morocco, I had a vague sense that my vehicle would have struggled with duals. When it wasn't sand it was stones where the singles didn't overhang the edge of the tracks made by landcruisers by as much as the duals would have.
The bit about driving technique is, IMHO, spot on. I'm no expert but there's sand, and there's sand. Moisture and particle size just add to the wheels and driving for an interesting mix.
I reckon the sand I was driving through was 37% more difficult that other sand.

According to USA Today, 85% of the people think their sand is more difficult than average.

Yes, but since they also believe that their driving skills are above average, it all balances out.
Fuso FE body builder's guide for 2004 shows the center of the stock front tire to center of stock front tire = 65.55" and center between two rear stock tires to same on other side = 65.35"

I would certainly say the Body Builders Guide is more actual then my measurements.
I re-measured today and got 61 inches from drum face to drum face in the rear and 74 inches from drum face to drum face in the front (tape measure accuracy).
Using those numbers, this is what I came up with for tracking:

This is another pic that does not take too much imagination to see the advantage of the single. So if you guys can fab me something to mount one in place of the two on the rear, I will be right down. Let me know. I attached a pic of the rear of my rig.
Right now the two spares are mounted nicely tucked in. I would only need one.
